Too sick

I feel so sick and it hit me out of no where . I took off work because of a snow storm on Thursday and called out again Friday because I felt so nauseous and been in bed again the whole day the last four days . Haven’t gotten out of the house . Between feeling nauseous and then constipated and then diarrhea. I have no appetite- here’s to 7 weeks and 5 days - when does it get better ? :(. I know I have to eat something other than saltine crackers
