It sucks to be sick and not know what is wrong. For a month now I have been dizzy and light headed and no matter how many doctors i go to they can’t figure it out. Countless blood test and a MRI and nothing. It is putting a damper on my life and stressing me out. I wonder how long I can keep doing this. I can’t even work full days and I am terrified of being fired because HR doesn’t understand or care.
