"Whatever that happens, it's for your own good"- Master Shashi

My yoga teacher said this. He mentioned that when you are depressed, feeling down or disappointed for some reasons or the other, remember this phrase. Quite apt for me. He mentioned this on a Monday, and I realise I have been using the phrase on myself for the whole week. It does console me for while, but I have allowed grief to overcome myself and I find myself tearing again...very badly. Never in my whole life have I teared so much in a job. I seem to be screwing up things quite badly these days. I am beginning to feel so useless... :(
Confidence shattered...Dreams shattered...Hopes shattered...Morale shattered...
Should I give up? "Should I stay...or should I go?"
