Chronic exhaustion years after ECT?

I did ECT a few years ago and everything changed after. I became chronically exhausted, my brain just doesn’t work as well as it used to, my ADHD is seemingly worse, my handwriting got worse, I have giant gaps in memory, and I can’t seem to get anything done.

But the chronic exhaustion is killing me. I’ve seen numerous doctors and no one can figure out what caused it. But right before it started, I did ECT. So, I’m trying to see if anyone else became chronically exhausted after doing ECT. If so, did it eventually get better?

Thanks!
