I'm sorry you're feeling lonely and isolated with your illness. I think people have a hard time understanding - they might be scared and don't know what to say or do. Unfortunately some people are shallow - meaning they're drawn to people in a good mood and shy away when people are in a bad mood. I know it's not fair and frustrating. Maybe you could tell one of the nicer people, what they could do, when you're feeling like this. I hope you feel better.
