I'm home sick today, went home early yesterday and was out Wednesday as well. why is everything so magnified when you're sick?

I'm feeling down and very sad. I feel completely useless in my life (I know that's a sweeping generalization). I work, I feed my pets and go out with friends once or twice a week, but I want more. I know it's dangerous to look around and see what everyone else has and compare myself to them, but that doesn't stop me. I thought I'd have a family; I thought I'd at least be married by now. now I feel it's too late for any of that. I'm financially not where I want to be. at least a dozen of my friends and family are off on trips right now and I'm so envious. I have no where to go, no money to go anywhere, and no one to go with. I'm so incredibly lonely.

I feel like I'm in survival mode right now, which is no way to live. I know I will feel better soon but for now, I feel sorry for myself. can anyone relate?
