Not sure what to do help!!!

So I got a random message on Instagram. This person asked me to be there friend I said yes we been talking a little. She in the military. Needs a friend to talk to says she had no one in her life. Lost her parents. Her best friend slept with her boyfriend. I don’t know if I trust her. She has her identity stolen and has many fake accounts made of her. She wants my address so she can send some me some stuff. That she doesn’t want to keep with her like personal papers and such. She says she can’t talk on the phone and isn’t supposed to have one. She recently got hurt. And is able to use a laptop. We video chatted twice for a few seconds. What should I do? I want to help her and trust her but I don’t know. She says she has no one she can trust so that’s why she wants to send me the stuff. I told her no but now she is asking for me to help her set up a P.O. Box for her. Would setting up a P.O. Box if she is real be a bad idea? She couldn’t get my information then. The video call was like FaceTime.
