Sleep is vital. Without sleep, our coping skills cannot be used to their maximum potential. No one functions well without sleep. Add stress, voices, etc, on top of it and it's no wonder you feel out of sorts. If you can sleep, do that first... If you can't, seek out what things would be soothing and healthy for you and may help you go to sleep. Get some rest, then re-evaluate how you feel.
