Extreme tiredness

Ha • Sun, Oct 06

38+1 today, and I slept from 11:30 pm - 7 am, then went back to bed at 10 am and slept until 1:00 pm, its now 2 pm (UK time) and I could go back to sleep. I haven’t done anything that has exhausted me, I am just plodding about the house and shops here and there.

Is there an explanation why I’m so tired ☹️
