relapse *possibly triggering*

So, I've had problems with depression since I was 9, I am now 17 almost 18 and I still have problems. Therapists have been of no assistance, medication stops working after a while, and friends/family can't keep me from hurting myself. It's nothing crazy like it used to be, just a few cute or burns every now and then, and as ashamed as I am, I keep doing it. I dont do it because I want to physically hurt, I do it just so I can look at them. I dont really know why. I haea wonderful long term boyfriend..maybe stress from starting college? Fear of me and my bf growing apart in the next couple of years? I dont know..I don't even know why I'm writing this out, no one going to read it...I guess it helps me feel better..
