Undecided

I have been seriously thinking about resigning from work...after almost 4 years of working, I finally came to a point of quitting...it has become like a struggle for me to wake up and drive my self to work...everyday I would think about an excuse not to work even if I'm perfectly feeling well...i would pretend that I'm sick so I have a good reason to call in...I know there are days when you're just really tired and would just want to take it easy and just relax..but lately it has gotten really worse...it's not easy for me these few months to work and at the same time attend classes..I really had no idea that it would be this difficult to concentrate on both work and studies...I know I have managed for the past few months but fatigue and stress is really taking a toll on my health...I was planning to submit my resignation last week and supposedly I would only have until march 30 to work but then again I could not get myself to submit my resignation letter...it would just have been one click on the send button and it would have been sent...I'm not sure why but my intuition tells me that its not a good decision...my job is really rewarding, i should ponder on that before I decide on what to do...up to this point i haven't really decided yet, but for now ill just have to leave things as it is...
