disappointment in one's self

she uploaded two pics today because she has gotten behind and needed to catch up.
she has had a lot on her mind lately.
she was very disrespectful towards her Master the other night and was punished, yet it really is bringing her down, she is really disappointed in herself.
Master says that she needs to let it go, He isn't upset anymore, and she wants to do as He asks but the disappointment she feels in herself will not go away.
she feels she has really messed up very badly and she is getting even more upset with herself because she cannot let it go as He says she should.

*sighs* will this feeling ever go away???
