When I'm driving, I often find myself wanting to drive into a ditch or have a car hit me. I don't want to be seriously hurt or killed. I just want to be slightly injured and taken to the hospital. I think I just want something interesting to happen, because my life is so boring. I just don't know. Is it normal?
It seems that your life is getting monotanous. You need to do something new, something you've never done before. Go to a concert, take a trip so someplace you've never been to, take a class. If your life is boring, it's up to you to change that.
I also would suggest that you see a mental health professional. Any desire to harm yourself could be a sign of an underlying issue.
For me it's just becaus eI want to freak everyone out and stir them up.
