Idek what to say anymore

I want to share something but I am confused of my own self. I do not know if I am happy or sad or even know what is the problem is. I just felt empty and discouraged. My family typically hates it when I tried to express my problems and they would say that I am making this up for an excuse to not doing anything in the house. I basically lock myself in my own room and I don't even want to go to school anymore.
