<human>: I'm not the smartest man. I try to do the right thing. And I am terrible at understanding people. Just for context.

I met this friend a few days ago on OKC. We hit it off right away and we pretty much know all of each other's secrets. I don't even know how but we have over 3000 messages sent between us already. We've sent a quite a lot of sexual messages, but this is nothing sexual.

Anyway, she has something wrong with her where all her organs are failing her. Doctors don't know if she'll live a week or 50 years. She was reluctant to tell me this at first because whenever she tells someone they start treating her very differently. I can understand that.

Recently she's asked me to punch her as hard as I can. It doesn't feel right. I don't ever punch people. But she feels there's something to prove. It's kinda been back and forth. I told her I would only hit her in the shoulder. She reluctantly agreed. I told her I would hit her as long as she hits me as hard as she can first. But she wont hit me unless I hit her first. 

I told her she can't bully me into doing that to her and that it's not fair. She knows this. But she's asked everyone else and they've all said no, some yelling at her. 

What in the fuck do I do. I realize the simple answer is "just don't do it" but like she's really stubborn. And she's old enough to decide what is good for her and what is not. She's like literally begging me to do it. Idk. I'm morally fucking confused.

Can you provide a brief overview of the text?
<bot>: Friend wants me to hit her. I don't want to. But she's dying and ~~insists~~ begs me I do it. Please help. What do I do?
