Can someone share how they cope with everyday life with autism + PTSD?

Hello everyone!

(English is not my first language so I apologize)

I 23 (F) have been diagnosed with PTSD since I'm 19. Latley my therapist suggested that I might have autistic traits that could make everyday tasks for me even more difficult than with just having PTSD.

I tried most of the things I could find online about getting stuff easier done if simple tasks overwhelme you.
Most of the time my partner does the chores around the house and I don't know how much longer I can accept that, because everytime I see him cleaning/cooking or bringing my letters to the post office I feel extremely bad and I get into a depressive episode (don't want to go too deep into how I actually feel, don't wanna trigger some people).

Did anyone else experience something similar and can share their coping mechanisms/ how they got rid of this down feeling?

Any advice or feedback is appreciated, because every day the fear of him burning out and/or leaving me only grows bigger and gets in between our relationship.

(also I put it on NSFW bc of the mention of mental ilnesses)
