How to survive being the underdog?

My has been very abusive towards me. I am not allowed to have feelings of hurt and pain. My bro and sis take her side. Its to the point where today, my own mother, sister and brother did not come to my college graduation today. It really hurts like hell. I asked God, why me, why me? what did I do wrong? People can talks so negative about you but can not support you achievements in life. I am hurt. How to look to God for help?
