Ok so they tell me I am likely to have ASC what next?

So I survived for 50 years and then after a few communication issues and some reflection   I ask for a neurodiversity assessment.  Initially, they give me a dyslexia screening which indicates maybe ASC. The ASC screening indicates yes. I am advised to self refer to my GP for an assessment. Have done can take 12 months to 18 months.  I have become particularly aware that my emotions react strongly when conflict occurs generally but particularly when it occurs with family or close friends and also with management. I guess I am posting here as yesterday I found a particularly situation difficult which could continue. What am I looking for? Not quite sure maybe just to write it down. Ion
