I held a job as a library assistant for YEARS and never was broken by the job b/c it was low stress and up my alley. I think you just have to find a job that fits you well, (that can be hard!) You also have to learn to leave work at work. I think just like jattitude74 said you really do need time off to just relax and get in tune w/ your self some times. I hope all works out for you and just remember to leave work just where it is work.
