Chronic illness + loneliness

Is such a fked combo. I can't even talk to people if I tried because my brain fog is so bad. Humans are wired for companion yet here I am spending most of days in my room, walks on my own, even talk to my damn self. Sad. All I can do is feel sad for myself and hope my illness just ends me, I don't see it getting better,it's been 4 years.
