It sounds like what you are experiencing is way beyond anything I can comment on, but I'll put these anecdotes here in the hope that they contribute to the eventual solution. There was recently a blog posted here (which I can't find) that was nominally about video game development, but had a great post about the burnout and subsequent recovery from burnout by one of the game's developers. It answered for me a lot of the questions about how to get beyond burnout that I had been experiencing. To summarize, the author stepped away from coding for a couple of months. Only later, when his interest drove him, did he begin to dabble in it again, and slowly take on more again. I think the abstract solution is that there needs to be a recovery period where the source of stress and anxiety has been removed and the body and mind have a chance to get back to 'normal'. Personally I've found that major attention and prioritization to sleep and exercise and lots of time off (much less than 2 mo) has made a big difference. Also, finding a solution to the cause of all this for me, which was too much work brought on by others leaving, has really helped. I've also spent time thinking a lot about the 'why' I want to do what I do. I has been really good to ponder these thoughts (and think about the feelings they invoke) and I've found my motivation returning again since. Best of luck to you in figuring this out.
