Thanks Grace. I hope you're doing better. I think you might want to try taking caffeine to get it going. It will get you up for a little while and you can start building momentum on stuff like exercise (it's fairly cheap too coffee/soda/caffeine pills). I know it's bad to suggest drugs to people on a mental health forum but it's something to think about. It won't give you light at the end of the tunnel but getting out will distract you from thinking about the walls closing in (at least that's the theory).
