Meltdown or okay? Small stack, final two tables, 2 Axo blind hands

Would MAYBE have called the 3,000 extra to try and flop to it.

But I think that the right decisions here would either be fold or all in. With your 15,000 raise you're betting half your stack and pot commiting yourself, you have a better chance of winning if you move all in and better fold equity, as well as giving him the lowest pot odds possible.
