1. He or she constantly puts you down making you feel bad about yourself.

3. They always make negative comments about you.

9. They don’t care about how you feel.

If your friend has one of the characteristics most likely they are not your friend they just hang with you to make themselves feel good and to make you feel bad about yourself. My advice is no one deserves a friend like that. A friend should be loyal,considerate,kind,modest,and caring.
Freely expressing my opinions is what I do and making you mad is a plus
