I don't want to add to any problems but be prepared to go the distance with your Social Security Disability claim. Not just mental illness but 75% of all claims are turned down the first time. It will more than likely take a year or more for your claim to get approved. I speak from experience. I would have to agree with Lothlorien about returning to work. I also have an anxiety component with my depression and the thought of going back to work comes close to going into a full blown attach. Good luck and hang in there.
