I recently realized that I'm a terrible person.
What makes you think you're a terrible person?
Sometimes I think I'm terrible but at least most of the time I don't dwell on it.
There's nothing wrong with feeling down about yourself from time to time. If you constantly dwell on negative thoughts and think you're a bad person though, it can have a severe impact on your mental health. Be sure to think good thoughts about yourself too!
How do I think positive about myself?
You can think about the things that you like about yourself or things that you know you're good at. What are you looking forward to in life? What are your goals?
