distraught

I've lost hundreds of dollars by the click of a mouse.

I've been scolded even though I've tried my best.

But never have I been so distraught after getting my results; the bad results even after the amount of effort I put in.

I once mentioned, if I can't do well for this tests, I don't know how to do well anymore.

Now that it happened, I really don't know how to do well anymore. Sigh.
