No one likes to make mistakes. Being an independent problem solver is not always the easiest but it is necessary. It is the default action to blame yourself and feel bad about the mistake you have made. At the end of the day, learn from it and move on. Now you know better and better you will become.
Psalm 43:5 New King James Version (NKJV)
Why are you cast down, O my soul?
And why are you disquieted within me?
Hope in God;
For I shall yet praise Him,
The help of my countenance and my God.
Daughter of the king
