I don't think it needs to be locked. And I'm glad that you've finally found help.
Believe it or not, I used to be emo a long time ago. I was in almost the same situation as you were. I didn't take medication though; I just tried finding hobbies and finding new friends. It really did help me though. My life is still not so good sometimes, but I've learned to not let it get to me as much. The only thing that still suggests that I'm "emo" is the music that I listen to. XD
