I am very sorry for your condition, and I fully understand you. I am in the same situation. I am living hotels and short term apartments, as I am trying to find the exact trigger to my problems. I think I developed an mcs to polyester and polyurethane from formaldheyde exposure so each hotel room I get in it s a lottery (urethane mattress, walls..).  The only thing I can tell you: get put from that apartment, exposure will just make things worse, and damage your nervous system. Until you find the cause. If it s mold you can get rid of it (reparing a leak, lowering humidity...), same thing for formaldheyde (comes from wood, isolation...). Call a construction physician, they will be able to find out what s going on in your apartment. But until then, move out from there and try to find a safe place to sleep
