I definitely think you should see your pdoc and tell them the truth. I use writing in a journal to help me process thoughts and work out what's causing the underlying problem that's really making me feel stressed. I also try not to sleep in too much even when I don't have much on. Some days I don't succeed and sleep in till lunch but I try to schedule things in the morning to get me up.
Exercise helps to but it can be hard to get going. Make sure you reward yourself when you do something that's hard to do. Lists can help get through the things you need to get done.
Moving to a new place is hard so don't put too much pressure on yourself. Keep in touch with old friends and try to get involved with new people. It took me a couple of years to feel at home in my current city.
