I was in the hospital with viral meningitis for five days about a month ago .i seemed to have recovered, but in the middle of last week I was lacking appetite, and I haven t been able to eat barely anything since Wednesday of last week. I m still about 119 pounds, which is 10 pounds under my original weight. My menstrual cycle did start at a regular time on Friday. I feel extremely tired, nauseous at times, and I have anxiety very often. Is this due to the weight loss?
