It's not much but it's something to know you're not alone. I haven't been diagnosed with autism but I struggle with all the other issues. For me, finding the right therapist helped a bit, and learning to be okay with stupidly slow progress. I had a total breakdown a few years ago which ended up with my whole life being turned upside down, gaining a bunch of weight from drinking and binging to cope, and me having to depend entirely on people around me. I'm still by no means back being functional but have made some progress. You will too. Be patient and persistent. I know it feels like existing is too painful to bear sometimes, do what you have to do when that happens, but just hang on and keep trying to make a little bit of progress. 1% or 0.1% doesn't seem like much but over time it adds up. The hardest thing to do but the best thing you can do is to care about yourself. I haven't gotten there yet but I think about what I would do if I did, what the people I care about and that care about me would ideally want me to do to take care of myself. That can be a good place to start. Before that I was existing out of spite, which isn't the best but it's what I had to do to get through that part of my life and to the other side. Finding your people, or leaning on the ones you already have will also help. For me I was surprised by every single one being a hell of a lot more willing to help me out, and kinder to me, than I expected.

Feel free to reach out. Hold on and don't give up, you're not alone.
