Another symptom of over-stress "disorder". You are showing another fraction of what caused me great suffering/panic...you are working too hard. Need to reduce the load somehow. Since you are tied to school, school comes first(unless you want to invest more money and re-do everything you have done). The other option would be to drop out and focuss on the promotion. If your workplace cant work around your school situation, then they are only interested in their own interests. Not yours. Why would a place that values you enough to promote you not take into consideration your pressures from school? Afterall, they hired you knowing you were in school. Workplaces hire alot of young ppl going to school...its like a promotional fringe benefit. "I hired another student...Im helping a student get his/her education."

If you cant afford the place you stay or school costs...thus the job is ever more important...then you have a pickle. In that case, I dont know where you turn. But, hopefully, family can back you up.

But, it seems the most important is to reduce the work/stress load as much as possible. Think of all you do like a plant. What is most important to your health and well-being is closest to the roots. If you can determine what things are less important/crucial to your health and well-being, you can cut them out to nourish the core/root.

Just a thought.
