Not being happy with yourself has nothing to do with personality disorder.
I'm guessing that you are having trouble figuring out what emotions you are having.
Can't blame you. Men are conditioned to repress their emotions. We are not suppose to cry or show any feeling.
The fact that no one in life has ever shown us how to handle your emotions is another factor.
But IMO if your are feeling bad and depressed. FEEL Bad and depressed. Dont repress them. They are there for a very good helpful reason. That reason is for you to learn from.
