still sick

i have not been feeling well for quite sometime. people around me tell me it's due to a combination of work and not enough rest. have been feeling the toll. perhaps its because i am not what i used to be. age factor is definitely one of the major contributor to this condition. went to the doctor today. gave me 2 days off. despite that, i had to make a detour to school to complete a few things. seriously m thinking of throwing in the towels....put in my resignation as a senior assistant and go back to what i love doing most i.e teaching. am sick and tired of being at the back and call of others, i do all the hard work,someone else reaps the rewards. sampai bila ?
am set on going for a thorough checkup at pusrawi this saturday. perhaps then, i can get to the root of this prolonged illness. Must go .... for my sake.
