imbroglio, jam, mix-up, muddle,

I am in a muss right now. It's not right for me to whine bout what happened in school when actually I feel happy when I'm with my students. There's other thing that invaded my mind now that makes me sick. In order to forget it, I blasted my job! I'm such a mess!

A person gave me this...

"If you love somebody, let them go, for if they return, they were always yours. And if they don't, they never were. "

and I feel even sicker..
