Uh, yeah, you can get into trouble!
Go to your dr. right away and tell him/her. They can adjust your medication and/or put you on a diff't drug. I was diagnosed years ago w/ clinical depression and yes, I hit low spells at times, but no, I've never resorted to committing a crime (which is what you're doing - it's called arson, which is a felony.) Definitely get help. I feel for you, but go do something about it. Now. I go do something about it when I'm down that's legal - like, talk to my dr. or "take it out" on gym equipment or going for a run. Don't wait. You're going to hurt yourself or someone else if not. Good luck.
