I am 56 and was told that I have autism which I do not really believe I have.
I cannot get it formally diagnosed as I am "to old" according to psychiatrists yet my psychologist assures me I actual have autism because he grew up with two brothers who have it.
The funny thing is that while not believing I have the condition I felt over the moon in regards to somebody who knows more than I do actually identifying a text book condition.
I have seen other people who have been diagnosed have the same reaction and it is a bit like winning the lottery after years of confusion.
I have no idea about what caused your PTSD but you need to step back and breath before moving on to the next challenge.
Easy said as I know from experience.
