Physical & Emotional Abuse Support Group
Abuse is a general term for the treatment of someone that causes some kind of harm (to the abused person, to the abusers themselves, or to someone else) that is unlawful or wrongful. No one deserves abuse, period. Abuse can be emotional, physical, or sexual.
Most people are uncomfortable with themselves, so you are not the only one. It begs one to ask why most people are scared of themselves. Perhaps they just don't want to accept themselves as being imperfect or worse. Yet expect others to accept them. Any hint that they are exposed as unworthy can spark self-defences such as anger, revenge, jealousy, envy, greed, and any other forms of fear.
I hope you will seriously consider finding your own truth and learn to accept it. Many who don't can end up like your friend.
