Can I be honest with you? I think I'm going insane.
Is there a reason you feel this way?
I think my mental illness is an excuse for what happened.
I'm sorry you're going through this. You shouldn't try to self-diagnose. You need to consult a trained mental-health professional.
I just don't know what to do here.
You need to get your life in order and going and getting mental help would be a nice start.
