Should I?

I was depressed a little while ago and I talked to the school counselor since my mom wouldn't listen, but I still don't know what's wrong with me because my mom won't take me to see what's up. I self-harmed before but I don't do it anymore, and I'm getting better but I talked to a close friend and she goes to therapy. She invited me to go with, should I? I'm doing better now, but should I still try therapy?
