Everything points to mania from reading your post. If I were in your situation, I would go to the closest emergency room and tell them what you typed here. Why in the he11 would I do that? Because although you are not physically harming yourself, you are emotionally harming yourself. You are in what my pdoc refers to as "self distructive mode. You need professional evaluation. Probably some inpatient time as well so you can get help. I am sorry you are going through this right now. Will you please check in at the emergency room? If not for you, but for your daughter?
