That sounds very tough. I have suspected I am on the autism spectrum for some time (they no longer use Aspbergers as an official diagnosis, but that would fit me). I can't afford to get the official evaluation, because my insurance won't cover testing for adults. However, I did find out I may be able to do therapy and support groups even without the official diagnosis.

Individual therapy never helped me much either. Support groups helped me much more. There are many available for free on Zoom. You can try Support Groups Central | Live Online Peer Support Groups for Life's Challenges, Hey Peers - Where Peers and Support Groups Connect, and http://namimd.org/.
