Hey Phil,
I don't know if that Dx "goes away" but I do not think it should keep you from being a writer - why on earth do you think it would do that? You are writing now and your writing makes sense. Some of the world's greatest writers had staggering mental illnesses (mostly untreated) and still managed to create profound works. Do not give up on being a writer, do not give up on yourself - look to your strengths and use them.
Take care.
