uneasiness retrieves

hey ya'll im sooo sick i seem to get sick very easily i dont know what it is with me and getting sick but its driving me crazy and my boss isnt to happy with it either shes getting mad at me cause i have to call in cause i dont want to get other people sick when im the one that is sick. i mean if i have a virus i dont want to give it to other people. i think that i am not able to give my 100% one day but the next i could if i just got some rest would be better to do than go in and only give 50% and then the next day not feel anybetter and still give 50%. but still i dont think my boss has really any right in gettin mad at me cause im sick its not my fault im sick i eat health and i exercise quite often. i just get sick very easily and im not one to get others sick. so if anyone has away of preventing me from getting sick and keeping my job please tell me cause it may help me in the future..
