Tribulations Ahead

I am scheduled to resume work next week. It has me a bit apprehensive but I've noticed that I am carrying a certain optimism that things would be different. While I am certainly not expecting the circumstances of my work situation to improve, am certainly more confident about being able to withstand the more difficult moments when they do arrive.
Am expecting the trails to start from day one of my resumption next week. Of course it my even be more brutal because I will have a lot of catching up to do, at least on the first day. Being able to withstand day one does not also mean anything either, as it will be continuous trails everyday till the next leave, or my exit.
My biggest concern of course is accumulated stress. There is a way stress can systemically break down the most clear perspectives and leave us with nothing but coping mechanisms. It is something that has gripped me for the most parts of the year so there really is a lot of raw Faith am putting into my resumption.
I am hopeful because the last few weeks have been marked with renewed clarity - the type I haven't experienced in at least a year. I don't know exactly how things pan out but one thing I do know is that I will do everything within my power to keep up this feeling.
I'm not up to speed on what your job is, nor why you took a hiatus. is it a high-stress sort of environment?
