Cut your losses and run. There's nothing you can do.
send a msg to all her friends and family with paypal transaction screenshots
That's more likely to get you thrown in jail than anything. Besides, you can't prove that she was the one who made the transaction.
I highly doubt something of that extent could get anyone thrown in jail as the screenshots make it effectively factual and not slander. However, it seems like it is not the woman's fault as much as it is Paypal's.
Be wary accepting any deals with Bitcoin + Paypal. Bitcoin is designed to be non-retractable and Paypal is designed to allow people to dispute payments up to 45 days after transaction.
OP: You might just have to accept this unfortunate event as a loss.
