Mental health..?

I'm 15 yr old girl & have mental health issues and serious suicide issues. I have had TONS of help and support for the past years. I see an amazing therapist now and feel alot better in myself. But i cannot help seek attention.. it sounds bad but things are okay at the minute and i'm not too down. In fact i'm really good, accept for the fact i have 0 friends at school and i'm scared. I feel like i wanna run away for no reason.. i wanna take overdoses, i wanna make myself feel sad because i'm so used to been sad i feel like it's the normal me. I wanna run away from home and not tell anybody. Should i tell my therapist that i'm seeking attention and want to run away and feel low ? I'm so confused.
