What can I do about my mom? I feel like killing myself because of her.?

Damn hang on there buddy, youll be okay,thats some serious stuff right there though, you should talk to someone about it, cause that right there is verbal and mental abuse, equally worse than physical, but think about it,.hang on until youre old enough and ready to move out, and move on with your life, apparently she doesnt care about you or herself, lying about her "illness"...some people arent lucky to be born into loving families im sorry about that, but i advise you to hold on there until its time, one day justice will be served, hope you feel better
