You are yourself Katie. Maybe not your old self, but you are still you. I'd be pissed off too. I was fine getting around bald, but there was always the expectation that I'd get hair back once treatment finished. Losing tits is different, you know they are gone for good. Still me though. Ok, maybe a grumpier version, but my heart and soul is still the same.
As for psychologists, you need to shop around. Seeing a shrink is like going to a restaurant--one bad meal doesn't mean you can't get a good one somewhere else and everyone likes something different anyway. Do any of the ladies you have met on FB have recommendations of who may be more sympathetic? They are probably in different parts of the country, but it may be worth asking if you haven't already. I guess it's worth pointing out that a good practitioner may not necessarily understand or empathise with your situation, but they will be able to help you build some tools to help you manage how it affects you.
