Advice for newly diagnosed, with dealing with unfairness

Hello everyone,

I'm mid 40s chap, recently diagnosed with ASD, and just trying to let it all sink in. If anyone can ooint me in the right direction for some guidance on dealing with certain things? (On here or elsewhere)

I struggle with communication, and often become overwhelmed when responses to points or answers I make, don't seem to relate to what Ive said at all. Makes me feel Im going crazy.

I'm also very much struggling when things arent "right" or "fair", how things should be. Again, it becomes overwhelming  - but often I'm  unable to walk away or let it go  because its a core feeling. Moreover, there is a large part inside, that even thiugh I cant seem to walk away, doesnt want to either! Ive identified something is not right, therefore is must be changed... Help!
