I understand how you feel. I felt the same once in my life. I think you have a middle-child syndrome. It happens a lot in families. I have a sister and is a middle child and always a center of oddities. But we don't hate her

Don't hate your family. They love you for sure. Take time to prove to them that you are not what they think you are. That you can be someone. But don't rebel against them. You will not be successful in your life if you have hate in your heart. They're still your family and you still belong to them.

I think things like that really comes to most of the people. I started to hate my mom and family since I was 10 and it continued to grow, hate after hate 'till I reached my 20 yrs. But i realized that hating them doesn;t solve everything. That blood is still thicker than anything else. So i let their insulting words pass my ears and never minded. I tried to understand them and acted maturely. Silently I achieved my goals in life sucess after success. I passed my board exam when they thought I couldn't make it. I graduated college without depending on them. Now I earned the respect from my family because I have proved them wrong. I used to rebel but it didn't help. I realized that a problem cannot be solved by another problem. So I took things constructively instead of destructively. Now I am a successful career woman. I earned their respect and they look on me as an example to my other siblings.

Hope my story helps.
