Emotionally breaking down, sorry

I'm pretty down. My friends are so unreliable I think I'm just gonna give up on them, though I honestly don't want to. It's fun hanging out with them but they hurt me a lot. The day of the sleep over last week my friends took almost 5 five hours to dye their hair at another friend's house then come to my house. They got here almost at 11pm then complained that they were hungry even though I was hungry too and had been waiting the whole time for them so I could order pizza and it would be warm for them. Then we were supposed to got to the beach to a bonfire and I invited my sorta friend Alan who I haven't seen in a while. They told me we were getting a ride from someone and I told Alan to meet us at the beach at 3pm on facebook because I don't have his phone number. I waited for my friends and we ended up getting there at 5. Obviously Alan left by then and I couldn't tell him we were gonna be late so he was gone when we got there. Then we only stayed for an hour because one of my friends didn't wanna stay, it wasn't even dark yet. And finally Friday my friends abandoned me completely. Three of us are done with the semester but the fourth still has not (we each go to different colleges). They decided to just go with the fourth to her school but it was too early for me since it took them until midnight to finally decide on the plans and I can't run on 4 hours of sleep (since her class started early). They wanted to go with her so we decided that they would go and afterwards meet me at a Starbucks near the trolley station one stop over from my stop (though it still takes a while for me to get to it) where they would normally get off to head home since they rode the trolley to get to her school. She got off at 12:15pm so I thought I would leave my house at 1 and get to the Starbucks around 1:45 and wait for them because the trolley takes about 45 minutes to get from her school to the stop. I got there at 1:40, text my friend (got no response), and waited until about 2:30 when my friend finally responds and tells me that they haven't even left the school yet. I got upset and was bored so I went to the mall another stop over. I thought since I'm always the one who has to message them to get information I'd wait until they text me to tell them where I was. I was in the Comics n' Stuff until 5 when I bought some comics and left, tired of waiting for them. I get home  at 6 and notice a text I hadn't seen that I had gotten on my way home. They told me that they decided to get coffee at her school and just headed home afterwards and never even went to the Starbucks. I don't even like coffee but I had agreed to meet them at Starbucks. If I had stayed there until I finally got that message I would have been at that Starbucks for 4 hours. They couldn't even bother to tell me they weren't going to show up until after I was heading home. I know "it's who cares? you left anyway" but that's not the point! They waited 4 hours to tell me they weren't going to show up. It's even more infuriating because the friend who's school they were going to cancels on me almost every time at the last minute. It's hard for me to just break it off is because 2 of them have been my closest and longest lasting friends and currently only friends including only one other. We have been friends for 5 years and even lost communication for a year when one moved away and I changed schools. As soon as she moved back we instantly talked to each other agin as if no time had passed. But recently they haven't been so close. The reason they are my only friends is because I have trouble talking to people and even when I do have a group of "friends", I just fade into the background (not purposely). I never get invited to hang out, I'm not invited to birthdays, and we eventually stop talking. They wouldn't even show up when invited to my birthday parties. I get along with them but I'm a quite person so I guess they kinda lose interest in me. It's beginning to feel the same with these friends. It hurts most because with the other people I don't have time to get attached but with these 2 friends I have grown extremely attached to because they were always there for me and I never faded because I'm only quite until I get to someone better, then you can't shut me up. Unlike with other people, I didn't have to be the one to always asked to hang out and force the friendship to continue. With these friends I was always included, I'm invited to birthdays, to hang out, and they come to my birthday parties. It wasn't often that we hung out but we always text each other  or talked on facebook. They're the only ones who have ever slept over to my house. But recently I feel like I'm fading in a forced way. I know they have new college friends because they are a lot more social then me but always canceling and abandoning me? That's a lot different. They've always had other friends and still kept in touch so that can't be it. I'm still talkative and social with them. My heart is breaking because even though I was used to being alone before them, I had finally made friends and have had them to talk to and we started hanging out a lot after we finished high school. That first semester and half of second semester in college was awesome, then suddenly it died. I feel hurt and I can't hang out with them anymore because I know they'll just hurt me more. I'd rather be alone again then constantly being hurt.

I know some people might think I'm being over dramatic and I know some people have it worse but this is what's happening to me and this is how I feel. What is happening IS hurting me. My grandma always says to think about other people's problems and knowing that they have it worse and still go on will make you feel better about your own but it makes me feel worse because I can't even handle the problems I have. It's hard for me to go back into being a hermit in my room because my stepmom is forcing me to go out every day but when I'm home not even the usual method of engulfing myself into a fantasy world of movies, comics, and video games is helping me feel better. But I know eventually I will be able to. I just have to try harder to forget, like I have with every other person that has entered my life. That is actually what I do. I absorb myself into a world that's not real and the people eventually get pushed so far to the back of my mind I won't remember unless they are mentioned or I decide to think back. After they are pushed to the back of my mind I can come out of the world I have immersed myself into and am free to start the cycle over again should I make new "friends".
Sorry I'm being such a downer but I occasionally get extremely depressed and could go on about other things but bringing them forward from my mind to even mention would hurt.
Sorry. I said I was gonna add something new to my etsy shop but my attempts at immersing myself hasn't worked yet and so I am too depressed to make anything.
Toodaloo and make sure your "friends" really are friends.
p.s. I forgot to mention before that I like the 11th Doctor and have finished all the episodes on netflix. I'm going to try and find season 7 online.
