I Always Manage To Isolate My Self From Everyone

I just assume that people don't really want me there.
I had friends. I don't know if we're still friends. I drifted away. I'm just tired of always pushing myself in there. I'm afraid I'll ruin their friendship. I thought maybe if they really wanted me there, they would show some effort. Meh. I'm too selfish but it's really hard to feel like you're just forcing people to include you in their group. I'll end up alone forever at this rate. But who cares anyway? It gets lonely but I kind of like it.
