Hatred will destroy you. Hatred born of self hatred will erase your own identity. We are all human, therefore we all are a little in common. You're dislike for your parents is justified, otherwise you wouldn't hate them. However, if you allow that hatred to consume you, they win. The opposite of love is not hate; rather, it is indifference. Learn not to care, not to harbor an ounce of dislike or affection, and you will be free from whatever bonds that hold you.
However, I suspect that your hatred of your parents is a mask for self-loathing that you have for yourself and your flaws. If you want to be happy, you must love yourself. Love yourself, even your faults and flaws, and no one can ever hurt you.
I wish you the best of luck in your life, my friend.
