Why am I always hurt my families?

You tend to pretend with those people outside your family. You wanted to accepted and with your family, you cant pretend cause they know you and you know for yourself that you are going to be accepted by them no matter what you do. You pretend with people around you cause you want to be accepted.

You are the only one that can answer your question.... it is because we don't know all the reasons about your anger...maybe there are psychological explanation with this... and may be you are just a hard headed person and just looking for the betterment of your self and not for the entire family ( I'm sorry).I have an experience before that tells the importance of the family. I suffered from an illness whom I lost my voice temporarily and I lost the strength of my right hand...I'd suffered a lot...but my family take good care of me specially my mother who use to spoon feed me for my meals...that is the incidence that i realized that my family loves me so much...for they offer their time,money and care for own good...better for you to take the advice of people who have a spiritual or psychological background..

What you experienced may be experienced by everyone. I also experienced the same problem with you. Sometimes I vent my anger to the family, despite the problems I had not come from my family. I have repeatedly regretted it, but sometimes I go back to. Now I am trying to control myself. So I'm not easy emotionally.
