Hi Bompilsf,

As someone who has had mental health issues like forever, my first thoughts are these. Of course, I'm not a psychologist at all, but it's possible your friend suffers with very low self esteem; he feels less-than, anxious, yes, scared, and attempts to pump himself up with all the false bravado you described. It can make the person sensitive to perceived criticism as well. The alcohol numbs down the anxiety and low self worth, he's feeling.

I feel kind of sorry for him because I can relate, and it's a lonely place to be. Oftentimes, a persons unstable upbringing - so the psychologists and doctors inform me - can be a factor. Someone like your friend could really benefit from some form of psychotherapy, but to take that step would first mean he would have to see himself as having a problem of sorts - which, at present, he may not.

Also, I'd just like to say he's lucky to have a friend like you. Good on you Bompilsf and I hope you get more insights from PC, as well.

And welcome to PC.
