My entire life I have suffered from anxiety and depression. This last year I was also diagnosed with Fibromyalgia. What all of these have in common is that they're all considered "invisible illnesses". There are a lot of days where I can't leave my house, let alone my bed. These conditions have ruined friendships and relationships. I try so hard to do as much as I can, even on my bad days. But it is so emotionally and physically draining to be in a constant battle with your mind and body. I am just now getting to a point where my friends and family are becoming more understanding. So, please, try to be understanding when your friends say they can't make it out to a party or event. Reach out to them and see how they're doing. Go see them. Hold their hand. Just love them. They really don't suck.
