No, not my brain anyway.
I currently meet a commonly used diagnostic criteria for severe depression, I am not depressed, it's just a lot of the questions are about not doing things which I can't do, because I have ME.
Literally as soon as my energy levels improve enough to allow my brain to run, even a little bit, better, I am attempting to figure out what, out of the hundreds of things I need to do, I should do, and how to achieve that. It's not a conscious choice, it just happens, I can't stop it. Of course until levels increase a little more my brain stalls out before any definite plan, let alone action, is achieved, but I know from experience, as soon as the resources are there I will be doing stuff, struggling hard to not over do it.
I've had ME for 29 years now, I'm currently at the severe end of moderate, I do not suffer from depression and I see no reason why, if I was magically "cured" I would start to.
