five hours isn't to much time, especially if the donation period is long. i can understand that it doesn't feel good, however.
0. find out what makes a good gofundme page-- a check for asking here, but there are other places online if you google.
1. the biggest thing that gets people to donate is connection. make sure your gofundme has personal stories, goals, and a very present human element so people will feel more connected to her, and more likely to feel giving. (pictures of pets can help a lot)
2.in the write-up, be humble, be upfront, and be hopeful-- even if you don't feel any of it. if the fundraiser hits certain milestones, thank everyone who's donated. be upfront about what will happen if the goal is not met-- no downplaying OR exaggerating why the cost is what it is. talking to the reader directly, thanking them for helping her reach her goal, brings in more connection.
3. expose as many people to the fundraiser as possible-- posting on social media sites is the most common, of course, but if you guys are in a community like a church a bulletin or notice to them can also be helpful don't be afraid to post more than once, but be careful not to spam!
4. there are some online groups in which people share their fundraisers, but it seems that each is for specific problems. i've seen one especially for queer kids, for example.
good luck, i hope this helps her meet her goal!
