I didn't know I was a broken person until somebody told me I was mostly a negative person.
That's a tough realization. When did you start to feel like you were broken?
I didn't notice it until somebody told me about it. I care about myself, but not enough to try to change what I can't control.
I can see you have problems, but being a negative person is wrong and won't get you anywhere in life. You should try focusing on your good sides and discover more positive aspects of yourself. Otherwise you will end up alone.
Nah I don't care about that.
I think you do care about it, on some level. I'll bet a little more positivity would really improve your entire life. No one can be upbeat all of the time, but everyone should try to be upbeat more of the time.
