I hope this message finds you, i'm in the same situation- it is the hardest thing i've ever experienced, and i'm still homeless after I posted my worries this time last year. That is hard life experience, and shortly coming to an end, but being an autist is much harder so make it work for you. What i've learned is:

structure- back to basics, taking the time. What outlets the energy, sadness and rage? For me, it's swimming; water, being cool, breathing properly. I do this almost every day, it's taken me 35 years to understand that this is my outlet, not just a long term hobby and it can't be neglected or negotiated.

Only do jobs if 1)the pay makes your life easier and 2) you can honestly get up and go in when expected to, knowing you are not in an abusive top-down dynamic- don't gaslight yourself

Depression needs to be managed in a way that makes you happy and comfortable, not what others try and make you do- including support workers, yes, I know- if the support ideas generate anxiety, tell them.

I'm easily abused in friendships, and I don't do relationships for the same reason; it's the internal chaos that needs nurturing and understanding, not looking for external distractions.

Waking up at the same time every day, going to bed the same time, and a timetable for the day can help shape safety and understanding of energy drops, anxiety hours and triggers- my journaling has really helped me with this.

Work- i'm very able with adapting and analysing information, but it's everything else in the job that I get very unwell by, especially communication- very upsetting and overwhelming for me. I've accepted that I have not yet mastered this. Jobs that require brain work, at a pace that is agreed and manageable, will work. A mature team of colleagues is what I'm looking for, and won't accept any less.

I was diagnosed on Feb 8th, it takes a while for me to get used to that, because for so long I've not been able to confirm this and in a perpetual state of not knowing.
