I am so sorry this happened to you. Sadly most cases like these are scams. One thing to keep in mind is that there will be other people offering you to recover the money, but that is a scam as well.

I’m not sure what country you came from, but most countries have so many laws to make scams like this difficult, sadly the US lacks laws and measures like this.

There is a good chance that the “girl” you were talking to is not even a girl but someone that does this for a living and you never stood a chance. They probably live nowhere near you.

Never send anyone money via Zelle, Cash app or Venmo, as you have no way of getting back that money. If you pay someone with PayPal don’t use friends and family, as that also doesn’t allow for you to get your money back, you should always select merchant.

In the future, if you are unsure if something is a scam, it probably is. If you need confirmation ask on r/Scams.
