I Am Confused

I don't know how to describe my feelings now. Nervous? Down? Fear? Fed up? Disappointed? Regretting? I don't know. It's confusing. I can't sort it out and I can't find the source. Maybe there are too many sources...

I am unable to control my temper and the mood is always oscillating between two extremities, just like the whether. It can be a super hot day at this moment and changes into a heavy storm the next second.

Everyone is busy with exams now so just leave them alone and disturb them with my problems after exam. Just focus on exam now and think about all those complicated things later.

I guess I am just tired, mentally and physically.
