Thank you everyone. I was upset when I made this post and I feel better reading other replies. As Licketysplit says, the statement is not exactly a compliment anyways. Angelicgoldfish05 touches on the statement being used as excuse, and that's what I was reacting to, seeing it as excusing harmful behavior. I mean how can you blame anyone of anything if they did "the best" they could?

But like Brown Owl says, my therapists may have thrown that out there as way of helping me accept things. Because it's real hard to accept things when you keep thinking or saying, "Why did/didn't he/she do that?" So to hear"they did the best they could" is a way to help you get in touch with people's and life's limitations.
