Normal? No one is 100% normal, so they say.
There are criterias for certain disorders, and believe me their are many disorders that many fit the criteria, and have not a clue, till they are evaluated by a psychiatrist, and/or psychologist.
Many of us go through a denial stage, the longer one refuses help the deeper the denial/resentment becomes, just messing things up more.
If a person is troubled with their own behaviour and/or sees the majority around them are having a problem getting along with you, it would benefit you to see a therapist, from there he or she may refer you to a pdoc, if it appears that you require one.
Refusing help or seeking it, is a hint too, that you just may have a problem. Life is much too short to be miserable, and cause misery, you owe it to yourself, to get help.
I hope you'll find peace, lots of luck with this.
