I have grown very close to a woman I met online. She is extremely intelligent, but I could tell she had issues. I did not know how severe until we finally met, at my insistence. I knew she had depression and anxiety. ADHD. That she had trouble getting things done, trouble making decisions, overall trouble functioning but on top of this, she cannot take care of herself hygienically, has a severe problem with hoarding and basically spends much of her waking moments crying or feeling scared/panicked. She also is clearly autistic though she insists she is not. At the same time, she is extremely sweet and has a strong sense of justice. She is truly a good person, I have never met anyone so honest. It's sad that we cannot make space for people like this in our society. She asks for so little to survive. I know I will take care of her for the rest of my life, but of course I know there are other people like her -- if she exists, there have to be others. She cannot work. She can barely function to take care of herself, and in some ways she cannot even meet that standard. She also lives in another country, so what I can do is limited and sending money helps but it doesn't help enough. I think she cannot be fixed but I would like to hope there is still a chance. She (and I) are relatively young, in our 30s.
