I think your first step should be counselling. If you try one and it doesn't 'click', try another. Counselling can be unbelievably helpful. Someone said to me once that she thought everyone should see a counsellor once every few years. She meant it as a joke, but after sitting with a good counsellor once myself, I agree completely. A good counsellor can help you put everything in perspective. One helped me out of an EPIC rut a few years back. Really: JUST DO IT.
