It's hard when your brain refuses to do things. I have ADD and sometimes my brain just says NOPE and won't do as I say. Also when I had depression I simply couldn't think, couldn't figure anything out. But life is complicated and it wasn't JUST this...

It also came out I was hypothyroid and it also made my mind weird. I had one spell of b12 deficiency, doesn't sound bad but if it is not bettered it starts killing off brain cells and other nerve cells. I had it despite getting enough in my food. Was a uptake issue. I also have low iron now and then and that gives me a very specific type of forgetfulness, I sort of lose what i did a few seconds ago. So either I try to do it again, or I forget to complete something because sidetracked. Not one thing here and there but all the darn time!

So it really does not even have to be one single thing.
