So tired..

Feeling so tired & exhausted lately, mainly due to "overworked". There's not enough manpower in the department and I have been doing EOD on calls or "Every Other Day" on calls for the last 5 weeks. Really tiring and exhausting. Some more, my on calls are most of the time very busy one, and hardly can get time to rest. Well, before i fully recovered, i need to do on call again the next day. I haven't even fully recovered from my previous Upper Respiratory Tract Infection or URTI and yet, seems like i'm going to get another URTI again.. Feeling feverish today with throat discomfort :( I need more rest but .... too bad, I can't, (so sad...) :(
