People can be so rude. See if it was me I would have responded and it would have said:
"Thank you so much for your great advice and encouragement. I hope that you will have a much better day tomorrow."
Im sorry you had to endure that. You know I believe that when people are mean like that, it always comes back to bite them in the butt! Karma is a @#%$.
Don't let the negativity discourage you.
