You do the best you can do in life, especially when it comes to your daughter, I’m sure. That is all you have to tell yourself. “I did the best of my ability, and that’s all that matters. If he (or she, or them, or whomever) doesn’t approve, or think I did good enough, I’m not going to let it bother me.” Say it out loud. Write letters to the person that upset you and get all your anger and frustration out that way (don’t mail them, of course lol). Hopefully, that will also be able to help you from arguing with the person, because you will have gotten your negative feelings on paper.

I hope this helps. They have helped me in the past. Best of luck to you. And just remember–every single person on this planet knows how it feels to be put down by another person. The hard part is choosing to not let it bother you.
