Hello nixnatasjanix,
Welcome to the NL BSS Hand Evaluation Forum! Hopefully we will see more hands from you in the future. I hope that with our help you can improve your play and as well move up the limits. We will be waiting for the next hands and till that good luck on tables!
Against that kind of stack there is not much to do. Of course it's ugly if he 4bets like this but as long we went for 3bet I don't think that we can fold here. Very likely even get a flip here.
Best regards.
