This is my first time on this site, and first time posting a thread so my apologies if I do anything wrong.

But, I have been having suicidal thoughts/unhealthy behaviors since I was around 11. I am 20 now, and am still having the same issues.
I was homeschooled my whole life, in a small town, with a very tiny family. Because of this, I did not have any friends and didn't socialize unless I had to. I didn't have birthday parties, I rarely took trips with my mom, sister, and somewhat emotionally abusive father.

My most common issues are feelings of worthlessness, loneliness, feeling undeserving, and as if no matter what I do I'll never be happy.
I guess what I'm really trying to ask, is if anyone else has had these issues, or knows how I can cope with them.
I apologize for my long rambling story, I thought maybe some details would help.
