I found grieving pretty helpful. I think that's something everyone with any long term dx goes through. You are still the same person before you heard the words, but you will grieve the person you *thought* you were, even if one and the same. It is like a loss, and all losses have period of mourning. Takes time and acceptance. Never easy tho.

I have accepted it now, but It took me about 6 years to get there, not kidding, but I really dug my heals in. And I wasn't here or talking to anyone else either, I think that might have helped me come to terms sooner.
