Keep trying and how to cope with "humiliation"

I know that keep trying is the best way to gain experience (which leads to confidence) and simply cause of the odds.

But what about the fear of humiliation? What about the overthinking and the fact that a failure is going to mark my psychology for the next few days bringing me back rather than forward.

How do I have to cope with the humiliation of a failed interaction? How is this humiliation going to influence my acquaintances' view of me?
