Legend no need to bag on the kid, hes going through a hard time.
That's disrespectful, anyways I understand what your going through not to the full extent but in the same way. But what I think you need to do is confront your mom on whats going on in your life at this moment, have a talk with her and maybe your sister ect. That's mainly what you can do for now , as for that maybe she will come to her senses and actually think about what she is doing. But I hope you can get through this, I'am sure you can.
