Vets/good with animals..HELP

Courtney🤘🏻 • I just want to cuddle my boyfriend and pet my cat. 👫🐱

I have this kitten, I don’t know how old she is, or anything. She was found in a ditch. I’ve had her for about a week now, and for the past couple hours she’s been puking up white stuff. It’s not really foamy, but it’s white and really liquidy. She’s not really eating or drinking. But whatever she does eat she pukes back up. I don’t have any vets open near me right now.

What should I do...
