And if so how? I am in my late 40s and outwardly probably seem OK. I don't think people would think I am especially confident but I sometimes do things that look as though I might be - give talks to large numbers of people, that kind of thing.
I have a lucky and fortunate life but MY GOD I have spent my whole life internally torturing myself with feelings of inadequacy. At the moment, these feelings are mostly focused on my career which I experience as a total humiliating failure. I punish myself for every mistake, I dissect everything I do and find it wanting, and constantly punish myself for that. It's so painful but I also know by now that if I didn't work for whatever reason, I would find something other way to internally tear myself apart.
Is anyone else like this and crucially what have you done if so? I have tried counselling and self-help books and sometimes they help a little but it seems my brain is set to function like this.
