Is it normal to be turning into a bitter, angry person?
For as long as I can remember, my dad has been the angriest and most hateful and cynical person I have ever known. Since I was a child, I promised myself that I would never become like him, because I felt that it would be completely miserable to live like that.
However, now that I'm in my early twenties, I feel like I'm starting to turn into him, personality-wise. I hate almost everyone, and I tend to focus on the negative and either ignore or trivialise positive things.
Is this a normal part of getting older, or do I have a problem?
