Need positive MANTRA

It has been months...
Workload is not an excuse but it is sometimes...

Have been keeping all the frustrations and anger inside.. trying so hard to keep it well inside.
Frustrations ... that sometimes makes you wanna yell out loud... but in the end you cool down..
Anger .... makes you wanna have confrontation ...but in the end you wiped out your tears...

Is that the strength that I cultivated thru all the hardships... or plainly blessing in disguise...
Think I should thank Allah for still giving me the strength...even though at times feel like quitting.
Quitting responsibilities? Exploring other opportunities?

I think I need positive mantra...
