I actually got referred through my doctor. Having said that not all cognitive therapists are psychologists.
I agree with you that if you haven't been in the situation you don't know what it feels like. I would even add that even if you have been in the same situation that doesn't mean you will react the same way. I had to get help otherwise my head and my thoughts would have driven my M back into the ground. I have every faith you will sort this out; recognising there is a problem in the first place is the biggest thing IMHO.
