I'm a bit confused. So before offering my advice, I'm going to try to recap what I think happened.
1. Potential buyer 1 makes offers - last pending offer being considered by OP/seller
2. Buyer 2 makes offer and it was accepted (prior to seller replying to #1)
3. Buyer 2 pays with e-check
4. Potential buyer #1 has a temper tantrum upon learning that someone else was "first come, first serve."
5. Buyer 2 wants to cancel -- probable buyer remorse but makes excuse
Since the e-check still hasn't cleared, go into your paypal account, click on the "details" and see if you're able to "refund" the full amount.
(I've never had occasion to issue a refund prior to an e-check clearing so I don't know whether it's possible.)
If you aren't able to cancel/refund, call paypal and explain that you want to stop the transfer.
After you've refunded the buyer, BBL both the fickle buyer and the hissy-fit sore loser.
You didn't do anything wrong. As with any listing, it's first come, first serve -- you snooze, you lose.
If you don't want her contacting you further, report her messages as harassment. I certainly wouldn't sell to her at this point.
ETA: Do not sell to the buyer for cheaper. This is yet another PITA looking for a lower price after having agreed to a price.
