At the mercy of.....

I often feel that I am at the mercy of my boss' temper. However, recently, I have to acknowledge that my colleagues are at the mercy of my temper.

Seemed that the more I pray for self control of my quick/hot tempered-ness, the MORE I get worked up.

I used to think that I am able to cope with stress/multitasking but I realized that I am absolutely lousy at it. Constantly, I keep having to pray to keep calm, keep level-headed. Somewhere midday today, I nearly burst out into tears (my way of coping).
