I work for a lawfirm and I handle all of our Social Security cases. I have many, many people that have various types of mental illnesses and are drawing disability checks based on that as well as other conditions. I have never heard of the government taking anyone away who collect disability based on the records the Social Security office obtained in order to make their decision to grant benefits.
I would strongly suggest, however that you do get an attorney to help you with your disability claim. The Social Security has a backlog so extensive right now that it is taking almost 2 years from the date of application until you are in front of the judge to determine your need for disability.
If you become homeless, your case can be pushed up ahead of time. If you attempt suicide, that is supposed to put a "rush" on your case as well, but I have two clients who have literally attempted suicide, and their cases have not been rushed, even after several letters to the judge to get it bumped up the line.
You are allowed to earn wages after you begin receiving benefits, but there is a cap on what your monthly earnings can be. I am not sure what amount that is, I know that your monthly earnings cannot exceed the amount of your monthly benefits, but if you call your local Social Security office, they can inform you of that. You just can have "gainful" employment.
I wish you the best of luck in your endeavors.
