Hi I am not sure whether me posting this will help or not but here goes.
I have posted about this previously but deleted it. I also have the same issue and suffer from BDD so I can associate with where you are coming from. Mine all started about 6 years ago, which coincided with the break up of a long term relationship amongst other things.
That was the day that I became massively aware of the fact that my hair was going, quickly and pretty badly. I never viewed myself as an oil painting but I could compete. Now you are one better than me as I am not sure I could post a pic in my avatar at the moment as it would mark the end of visiting this site!! However I thought I would post picture links below. These are from my wedding last year and as yet I havent been able to look at them in a positive way, which can almost make me cry just thinking about it as I want to be proud of them and remember the day. http://www.flickr.com/photos/49187552@N03/4509813395/http://www.flickr.com/photos/49187552@N03/4509817695/http://www.flickr.com/photos/49187552@N03/4509820791/
It is funny as everyone I have shown them to think they are ok, but I think they are lying and being nice. For me my obsessions are very similar to yours. I hate my complexion, I hate the shape of my head, I hate my flat face and I hate the amount of hair I have lost and how my shadow looks. In the past I have obsessed about all of these things sometimes for hours at a time.
I suppose I have quite a different life to you as I have a wife and child. I am not sure how old you are but I am 32 and really determined that this will not take over my life.
I too have just started CBT on my fourth session and what I would say is be prepared for a slog. There are some tough times ahead, but I am led to believe that this by far the best sort of treatment for this. Don't hold back, lay it on the line and dont view your problem as trivial. I know most people will tell you that it doesnt matter, but with BDD (for me anyway) it isnt the root cause of the problem as I know there are people worse off than me, but it is the irrational way in which it manifests itself.
Anyway, just wanted to let you know you arent alone and if you want to chat at any point I am only too happy.
