Stressed !! Should I just cut her out ?!

So my friend that is throwing my baby shower has done little to know help with it and we are down to only a couple weeks away with almost nothing done! I have made checklist for her and pretty much done everything myself up to this point. But she seems to just not care about the fact that nothing else has been done. My mom and sister from out of town have offered to step up and finish what needs to be done for me but I'm also skeptical about my sister being so far away trying to plan. I'm at the point where I want to give up. I was hoping to enjoy this baby shower and now it's a big mess. Should I just say screw it and finish myself or let my family try and help or hope she gets it together in time ? And yes I have gone over and over with her, made her list of things to get done expressed how stressed this is making me and it's like I'm talking to a wall.
