The world is made of unique individuals. There are those who actively seek the absolute terror of a roller coaster ride 1000 feet high and speeding at warp speed through a 90 degree turn. Others prefer a paddle boat ride in a serene river. You obviously have decided long ago you'd rather live in assured predictability and control of unexpected situations must be non-strenuous. You state you were an excellent student, but of what studies or major? You also state you disliked the jobs you had before because of the challenges. You have already answered the type of job you prefer, filing or data entry. There are plenty of those jobs around. But I suspect you're main issue is that you can't find a job you seek for near solitude quiet that pays well. So you may have to take the bad with the good, unless depending on your education, you can find employment as an embalmer where you will be guaranteed not to be disturbed, questioned or interact with more than one individual at a time who never complain. Or data entry and filing.
