Abby, Having a disease - or two or more - sure isn't easy. It does make you a different person than you used to be. And other people often don't like that change either and don't know how to deal with it well, as you know. It would be nice if others would at least treat us normally, as if we were not sick.
Don't you love to create? I can't remember what exactly it is you like to do but I recall that you liked to do that. For me, the two antidepressants I take are writing and creating/drawing (on computer). I need to do those things in order to feel good every day. I lose track of time, and my disease, and take my mind to a place where it may not even notice that my hand is cramping up or that my arm is really too weak to keep doing it.
There are times I simply can't handle MG and rebel. But, for the most part, I have come to some kind of "ok" place with it. It sure took a long time though. I hope you can find that balance between having a good quality of your life and battling this stupid disease.
I'm sorry about your Mom. I think you know what I'm going to say. Get her B levels checked (thiamine too) and her thyroid + antibodies. A basic chem panel to make sure her kidneys and liver are ok. There's a differential for Alzheimer's or dementia that's necessary to go through. I often say that older people don't die of disease, they die of malnutrition. Things like a lack of stomach acid, celiac disease, vitamin deficiencies (from those two or other reasons), metabolic mutations or so many other reasons can make someone "out of it." At the height of my B12 deficiency, I was talking quite loudly out loud around people in stores and not even knowing I was doing it. I thought I was only "thinking" what I was saying.
It was not a fun experience. And considering that you may have some genetic stuff in your family, perhaps a trip to a neuro wouldn't be a bad idea. Cholinesterase inhibitors are used in Alzheimer's too.
You've got a lot on your plate. I think we can all really relate to that. Sometimes getting a disease is a lesson others need to learn. Like how to adapt, be more tolerant, be more loving and considerate.
How would they feel if they had to do this with MG every day? Except it hits more than it misses.
It's times like this when others need to be there for YOU. There are people, however, who are wholly incapable of that. So you'll have to do some "caretaking" of yourself first.
