There are ways that Aspies can help themselves to not get so tired and end up having shutdowns. I have already said that I often take a nap in the afternoon. That is one way.
Someone else called it 'energy accounting' I call it pacing myself. I try to pace myself with going out. I don't go out twice in a day (or try not to), I try not to go out every day of the week, and have at least 1 or 2 days when I stay in and do other things that I like doing eg writing/typing or helping my mum in the garden and feed the birds.
It helps a lot that I am at home now and not working. I can do what I want when I want to, and that includes having a nap. And like today, if my head goes all funny and light because I have done too much, I can stop what I am doing and go to bed. Now that I have rested my head, I feel a bit more myself.
So, if you do work at home, try to have a nap during the day. You will find it will recharge your brain and body. Try to go out only when needed.
