I only wanted to help

Real quick question. What is she crying about. What did she want to help. What happened that was so bad. Why is she feeling so much guilt... Oh wait... I think this is supposed to be some kind of undertale reference to how some people feel about the way of genocide... Am I close. But seriously I have a lot of questions about this gif. Its slightly disturbing.

But I kind of understand that some people just go through some tough stuff. It may not necessarily be about anything. It might just be a way of showing how some people cope with their emotional/mental/personal issues. (P.S, Sorry if these comments are coming off as harsh, I am just curious and somewhat relate in my own way.)
