Failure is hard to take

I have been collecting 100 fails as a part of reaching my 200k revenue goal in my Architectural practice.. And this happened..

C The client decided not to proceed and gave feedback
T I made a mistake / I failed
F Shame
A Lose confidence. Stop working for the day. Want to curl in a ball. Don’t want to speak to people

Am I dealing with my fail badly and what should I be doing instead to turn it into a positive? I realise I expect my clients to be grateful or at least have a kind and appreciative word for the work I have done for them. When this doesn’t happen I can see my confidence drops.
