Wow, I missed that.
I also remember being sensitive to that kind of criticism, and in my case, the problem was I really believed I must be getting everything wrong and every criticism was valid. In the end, my perceptiveness improved over time, I had some CBT which raised my self-awareness in such situations, and - probably the most important thing - I gained some good support networks, in the form of colleagues, orchestras, even people like my piano teacher - you can find good allies in all sorts of unexpected places. These aren't people I bring every problem to, just people who like me and I know it, so that I don't have to go through life blaming myself every time someone doesn't.
Everyone's problem is different, but if Neil is still reading this, then there's a checklist - see if any of that is missing and could help. The comment from Edgar should really have stayed in the thread it related to, but it's worth finding ways to be more resilient to curve-ball criticisms if you can, since you never know when and in which community the next one will happen.
