Coming from someone who more than understands self hate, thinking horrible things about yourself can really destroy you. What you think of yourself is much more important than what others think of you. Words have power, therefore, what we speak over ourselves has just as much power as the curses we speak over others. So it's best to try your hardest to see your greatest qualities rather than your flaws. And if you can't, find someone who loves you enough to see the good in you and will remind you of it every day.
