Hi i'm new and not diagnosed but should I ask

I am 49 and when I was around 18 (1990) I was diagnosed with Depression. Since then, I have had Counselling with various people and various forms (mainly CBT) and various medications.

In 2005 I was diagnosed as having Chronic Anxiety, In 2019 I was told I had Generalised Anxiety Disorder.

2 years ago, something devastating happened which was profoundly serious. I was in a situation where I reacted violently towards someone, I have no knowledge of what happened as it’s a complete blank, I have found out through CCTV and statements taken at the time of what I did, and it is something I didn’t think I was capable of and without going into specifics I suddenly exploded then shut down (sorry its the best way I can explain it).

After this event I have found it exceedingly difficult and was under the Crisis Team where I have also been diagnosed as having OCD and have been through various teams since.

A few times while passing though these teams and having counselling, being Autistic or on the spectrum has been mentioned but I dismissed this as I felt this meant being like Rainman or being a genius who no one can understand. But I recently saw something I think on tv which showed this was extreme cases and people who are Autistic are effected in various ways.

I started looking into this on the internet with trusted sites (NHS and autism.org.uk). I can see quite a few signs which fit with me, but I do not know if I am making them fit to explain what is happening to me or if I actually fit into this category.

Should I speak to my GP and ask for a test, but then I don’t know how to approach this and go though scenarios in my head where I’m dismissed off hand or told to not be silly, so not sure what to do if anything.

Regards
