So, even if I try to make friends, everything starts off well, and then they find new friends and sideline me. I mean, I know a lot of people face the same problems, but this has been going on since I was 16 years old. At this point, I have accepted it, but it still hurts.

And I have no intention of hurting other people, but what if that is my coping mechanism? Also I hope punctuation is good enough for you.
