If you can, consider to volunteer at a shelter or any volunteer activity that you find accessible to you.
I say this specifically because giving to others is undervalued for its internal benefits, and animals tend to be more accessible to direct love towards than humans with their complexities. But overall just giving is a way of transferring some of yourself into a more together context, and volunteering tends to be socially easier than like hanging at a bar or something...idk, just another autistic person who has/does struggle with depression in many contexts.
Volunteer at a cat shelter for e.g was only a tiny part of my burn out recovery process but it was still a really important catalyst and component. Maybe you can have some similar experiences too! Or maybe your own experiences are very different and it's not valuable for you, I'm sorry.
If you want I can ramble more about structural reasons for why this is a very good idea for autism+depression, but the point is really 'one extremely small and accessible suggestion' and so I don't want to overcomplicate it more.
Anyway if animals can't work for you, any other volunteering and/or metta/ loving-kindness meditation would be my second recommendations.
But it's really important for the volunteering bits that you are not maximizing efficiency. It is certainly 10X more impact if I was to work$ and donate that to the cat shelter. But in terms of the thematic healing goal, it is more important I spend time scooping poop for the cat gods at the shelter almost precisely because it's not a utility-value driven experience. Giving unto others, etc.
