I've lost my aunt and now losing my mother to it. It's a garbage diseases and such a burden on the loved ones, mental, physical and financial.

I'm so sorry you went through that.

I lost my grandma because of this. She was taken care of by my uncle and my father, and deep in my heart, part of me blames them for not doing their best. At the same time, I know they did way more than I ever could have done. It’s just so hard to take care of someone like that.

I don't even know what "best" looks like, tbh. I also have some family not particularly happy (putting it nicely) with how my uncle handled it. I personally think he's a saint; views differ but there's no Right Way, I don't think. Everything is clearer in hindsight, too. It's just a severe, extended period of sadness and loss, I don't know how anyone actually dealing with it can do it for that long aside from intense love for the person. It's one of the most unrewarding things I think you can humanly go through. :/
