I wake up about 3 out of 7 days with a headache and feel sick all day....fatigue, muscle weakness, irritable. I am taking dextroamphetamine for fatigue and lorazepam to sleep. I believe I have something physical going on because I have had positive blood test results and a "possible connective tissue" diagnosis, but nothing specific. Lately I bring up negative things at work and can't say anything positive and I cry very easily (at home) because I don't feel good. Is this depression?
