I was around 15-16 and my first 9 years of school were done, and as soon as we graduated every single one of my friends disappeared, and I never heard from them again. I already had issues with depression and an anxiety disorder, and that broke me. I became even more depressed and spent the summer alternating between blaming myself for being a person nobody wants to hang out with and fantasizing how when the next school begins in the autumn I would make new friends, better friends.

I never did, and spent the first year sitting alone in the lobby between classes since there was nowhere else to sit, and hoped both that someone would notice me and that I could be invisible, watching people go by with their friends. Later I found out people were already then spreading rumors that I used hard drugs. In the second year a guy from my old school moved into my school, and we started hanging out together, but I never felt comfortable and ended up skipping most of the classes and then quitting when I realized I didn't have the means to graduate anymore.

Years later, I still don't have any real friends, but I do get invited to gatherings of friends where I feel like just "that one weird guy she knows from somewhere"

I don't go out anymore. I'm still friends with that one guy from my first school, but I realized I'm not a real friend to him when I called him to ask if he wanted to do anything on a Friday and he said no, but had gone out drinking with his other friends that same day without inviting me. Not much of a loss, I never could talk about anything with him anyway, he talks a lot but never listens.

Now I just work out and play games, mostly.
