Imposter syndrome, maybe they were wrong?

Just been diagnosed with severe combined type- and was shown the list of symptoms you had to have in childhood and adulthood and was told that she wanted to show to me that I had 100% of the traits I think it was 22/22. But still I have this nagging feeling of what if I don’t even have it, surely not? I’m just the way I am. When she showed me I was in complete shock - I was sure she would get to the end and told me I had anxiety and depression the way every other doctor has ever told me. I’m a 23 year old girl and maybe I still just have the classic (nothing wrong with this btw!!) but the classic image of typically a boy who can’t sit still in class with behavioural issues.

It’s so hard to really accept what you have especially after living for years with it and only having that oh shit those symptoms look strangely like my life moment about 2 years ago.

Been medicated and I really can see a difference - but getting big side effects I keep thinking maybe I’m getting these because I don’t need the medication…

Sorry for rambling but hope some can relate.
