I get that fear a lot too. The more depressed I am the more that fear takes over. Right now for me it's not that bad. I'm trying to enjoy every bit of life I can. What I'd do as much as I can to distract myself from it - by watching TV, playing a game, going out with friends, whatever is possible. Also trying to enjoy the very small pleasures as much as I can. Dunno if that helps but I hope you can find a way to relax some
