How could I possibly destress?

I've a house to keep clean, with no one else to do it for me, and I've always been more productive at night.

I might have hypomania, along with the insomnia. The Autism doesn't make life easier, though. Up all night, tumble-drying clothes and towels from half three to ten past eight. (clothes and towels dried separately)

How is it possible to destress? I've done meditation before. It's just temporary relief. Then back to the fun house.

Apologies for the rant. I'm meant to take my friend and I to Lidl later today.
