I've noticed parts of my autism getting a lot worse over the last 5 or 6 years, specifically my overthinking, analyzing things that have happened (events, conversations, things I've done), health anxiety and general worrying. I do have dependents and recently increased (by choice, long story) some financial burden (quite manageable, just bigger) and I wonder if these are the 2 main stressors that are triggering it. Not really much I can do about it other that keep telling myself that everything is ok, stop overthinking, I am not the expert in the things I've trying to analyse.....but it's hard!
So yes, things can certainly "get worse" by whatever means you chose to measure the level of impairment.
On the plus side, over the same period my ability to deal with social situations has certainly got better - mainly because I've been forced into more of them with having kids, so I've had to up my masking levels. I must say though, whilst I've got better about it, I care less about doing it now - maybe it's an age thing, and that's normal with most humans, I don't really have the energy to bother with social situations where I don't need to be in them.
