Jesyka, I think it’s just the other way around.
You can’t base your self-esteem on others’ behaviours or reactions. Self-esteem has to grow or be repair from the inner.
We can’t depend so much on what happens outside. If we would do so, we were like leaves moved by the wind. Our mood would depend on what others may think or react with us. And even worse, would depend on the reasons why we may think the other person is acting the way they are. Most of the time, a wrong assumption because people make mistakes, there are misunderstandings, we have all our mood at different moments, circumstances, our beliefs (maybe the rock star believed he was only being cool, making a role at the stage) who knows.
I’ve been to a concert where the group began to insult the audience and the audience threw them tins, plastic bowls and all. They then, returned these to the audience. And they were a very famous band.
It’s very important that your next therapy work with you this point about how to repair self-esteem and also, help you with mentalizing so you will be able to reach a better comprehension of your own behaviour and people’s one.

Mentalization-based therapy (MBT)
