We can't choose our family, but we can choose how we live our own lives. Parents make mistakes just like everyone else. Some are good parents, some are selfish neglectful parents. Some make intelligent decisions, some not so much. It is up to us to take the good and leave the bad examples that our parents give to us. We can not blame them for anything that happens to us once we are old enough to make our own decisions. So, that means that no matter how bad things are you can improve them. You can start working on making a better life for yourself.
I can't believe that you would allow the mistakes that your parents made decide your future. You are a strong person that can change anything in your life that you want to change. You can develop a nice personality. You can quit cursing people. You can get rid of that negative attitude. You must think that no one else has problems.
Let me tell you that my step father treated me like I was nothing. He tortured me by calling me names, and he even molested me. He threatened my family if I told anyone, and I felt hopeless. I decided that no matter what happened, I was going to end up with a happy life, and I did. I started by ignoring his remarks. I looked at him, and realized that he had nothing to offer me in the way of being a role model, so I excluded him unless it was absolutely necessary to talk to him. I looked for good role models. I searched out people that I admired and respected for some reason, and learned from talking to them, and observing them. I worked on my personality, made myself more stylish, learned how to speak properly to people, went to school for an education, and now I have a wonderful life. I left behind me all of the disappoints of my past. I still have disappointments, but I NEVER let them control my life. I am in charge of this life, and I plan to make the best of it.
