Diagnosis and work

I’ve recently had my autism assessment and get my results Friday, I’ve been off work signed off by the doctor for various reasons since beginning of February. I’m currently also caring for my daughter full time who has mental trouble and is also autistic.

work seemed to be understanding but now they keep suggesting returning to work but I think they think I just sit around all day I don’t know what to do. 
I think if I am diagnosed it will answer many questions I have had over the years but I also don’t feel as though I could return to work!! I’m exhausted at the thought of it!!!

my dad for is the one working at the moment and I wish I could just leave my job as I feel as though I have a rope holding me down.

im really confused all I want to do is care for my daughter and make sure she is ok
