4 hours ago one of my closest friends jumped off a building, and I just don't know what to do.

She was at my class and was giving no signal whatsover that she was going to do that.

The worst part is that I probably could have done something about it, I mean she was literally in front of me for 8 and a half hours today, and I didn't do anything to stop that. I am feeling guilty af and I don't know what to do about it.

I wasn't her only friend, in fact she was kind of popular. But I still feel like I could have done more for her.

If you are close to that state please ask help to one of your friends, family or a professional. It does not need to end there.
