I can relate. All the criticsim and never being good enough.
Negative self talk is now a habbit for me. I'm good at that.
It's not true though.
Remember to give yourself praise and credit where and when it is needed.
Would a friend call you stupid for the spilt water? What would a friend say or what would you tell someone else who spilled something?
It's ok. It happens and can be cleaned up. And that is what happens.
So ask yourself what would you tell someone in that situation?
