negative to positive

i am becoming a person that i really hate. i hate negative people. i hate people who question their worth and then rubs off negative vibes to people around them. yet this negative thinking pattern is taking over me and i hate it. how do i reverse the situation? motivational quotes seem to lose its effect on me. what the fuck is wrong with me? Lord, please help me so i can help others. no amount of meditation seem to work. oh fuck it.
