Blind battle against very aggro opp

[Vinny80]

Villain is somewhat lag 23/19/5 and is decent. I'm wondering what's the best line here. Preflop I'm mixing it up between reraising, calling and even folding but we're kinda deep here to fold in my opinion. On the turn, what do you do here or does anyone raise the flop right away, and why...
