I don’t know what happened

3 years ago, I had lots of friends and following my dream!

Suddenly, I’m cast aside, it’s all ground to a halt and now I can’t even get someone to have a drink or watch a movie with me.

And the worst thing is I have absolutely no idea why, I try to be nice to everyone. Why is this happening? I’m turning into a lonely, bitter person and as much as I try, I cant seem to change it.
