I hear voices in my head, i cant control my emotions that well, i see a dog sometimes its rare but dose happen?

The voices in your head will be something called OCD, it's a common thing and it can't harm you at all. It could just be to do with high stress or just because you have it anyway. The best thing to do is talk to a doctor and they might send you to a councillor and the councillor will help you make sense of it and then you will be able to manage it ok. And the same with not being able to control your emotions, a councillor will be able to help you with that too. Don't worry yourself though because your not ill or anything, I have the same things myself and I have a councillor that helps me. So talk to a doctor and they'll help you.
