Best way to learn to draw with early Alzheimer's

Hey everyone,

I'm not going to write a sob story, but just something short to explain my situation. I am a 30 years old guy living with my mom. My dad went off to marry another woman to start a family. So it's up to me to take care of my mom by myself. However, my memory lapses such as forgetting how to tie shoelaces made me get checked and yeah it turns out to be early alzheimers.

A lot of my time is occupied but I just really want to draw before I kick the bucket. Drawing tablets are cheap and my brick of a pc should be able to run a free drawing app. I want to draw some anime style drawings or something like a gundam but I don't know where to start. I don't think anyone will be in a situation like mine, but I would like to know how long it would take to get 'good' or 'pass' at being able to draw, or if there is an accelerated method to learn how to draw better (like taking some class). You can give me just a link and that would be helpful, and if there are better subs to go too for what I am looking for I would appreciate that as well. Thank you.
