Deeply disillusioned with human beings

After having to fight a lot to get a fraction of the help I need with this illness, and hearing people's opinions, it has shown me a lot of people understand almost nothing about this illness. But they think they do, and they are ignorant in negative ways. I am so tired and feel very alone. I feel uncertain with people because I keep getting disappointed with them. And really I am starting to hate a lot of people in general. Does anyone have this and how can I regain my faith in humans again?
