How should I deal with constant anxiety problems?
spaghetti: Take a break from computers.  I notice an increase in stressful thoughts when I do too much programming.  When I take a break from programming all the stressful thoughts vanish.  I know "taking a break" from programming can be hard, especially if it's your job and you have financial obligations.  In my experience taking a break of non-trivial length (1 - 6 months) has substantial rewards.  I quit my comfy job around the middle of last year.  I took 6 months off and am now back in a similar job.  I feel far better everyday and I'm at least 1.5x as productive.  I hope your situation will lend itself to a break like this.
