I'm thinking about killing myself after my mom dies
Is your mom close to death?
Yes, she has terminal cancer
Hey the last thing she would want if for you to kill yourself. You need to be able to live your life until its natural end.
I won't kill myself but I don't see what is wrong with it.
Killing yourself is robbing yourself of a future. You will miss so many opportunities. And some poor person would have to find your body and clean up the mess which would be traumatic.
