I would suggest putting academic work to the bottom of the list for now.
Instead: What are your child's triggers for stress? (people can't learn when they are stressed). Which of them can you remove? What tools might help with others? (ear defenders, ear plugs, conversation while walking or climbing or stimming?) really concentrate on what YOU can do to help make the surroundings comfortable. And ask your child what makes them safe, happy, relaxed.
Make a list of things you want your child to be able to do. Cook independently? Manage conversations in shops? Decide on a shopping list and find and buy the stuff? Wash clothes, hoover? Cultivate vegetables? Look after a pet? Manage social interactions? Work on those, in an apprenticeship model.
Try to find a few likeminded people to see. Again, your child may need much more support than many children - help them interact positively and productively. Get them into the UK home Ed Minecraft community (there are lots of autistic children who play Minecraft together over skype, apparently. Great way to manage social interactions at one remove - be on hand to guide and support).
See if you can find one regular activity your child will love, which is led by someone not you, even if you are there helping. Riding, football, martial arts, swimming, nature walks, coding club - whatever! Gradually, that will become a place you can take a back seat, and your child will build their confidence in successful social interaction with other adults.
If you can find a community.home Ed group, that's a place to start meeting.people. Often, people use our local Facebook group like a play date dating agency "5 year old, loves x y z, looking for likeminded children to play with". The other parent then is someone for you to chat with, increasingly as the children get more comfortable around each.other.
You're about to go through the looking glass. All that pressure competition anxiety school stuff isn't really relevant in.home Ed land. Here its about helping your.child grow into a happy and independent human being, by.following their interests and needs along the way.
Nb I'm not saying don't do academic stuff. But DO step back from anything that looks.like "work" until after the summer holidays. Enjoy each other's company again - rediscover each other's interests and personalities. Many people talk about it as if they got their quirky, creative,interested 3/4 year old back, after that person had been buried in anxiety for years. But that all takes some.time for.decompression!
