I know this probably goes without saying - but, I'm so tired I'm crying. I dont know what to do. I have to work. My son's graduation is tomorrow, his party Saturday. I'm a single mom. I feel I am on a slippery slope here with fatigue. Every day I get worse and worse and worse - even only a small degree, but worse nonetheless. I'm not sure what to do about this. I tried taking Ritalin, but it made me very ill, so I had to quit. Any advice? I'm thinking of asking the doc for a note for like 3-4 days off work, but I'm not sure. I'm afraid of losing my job.
