Has anyone received disability while working part-time?. I'm caught in a catch 22. I substitute teach on the days that I am up to it, but I can't work enought to support myself. How can I convince the SS. that I am disabled? It is impossible for me not to work at all. I have CFS, PTSD, Asthma, neurally-mediated hypotension, Sleep Apnea - I cannot use CPAP (IT HELPS FOR A COUPLE OF DAYS AND THEN I GET A RESPIRATORY INFECTION. IT HAPPENS EVERY TIME), allergies, insomnia, depression, anxiety, poor concentration, short-term memory problems. I have probably left some things out. Can't remember everything that is wrong with me. Thanks for any advice you can give.
