my biggest leak: AK

Hand 1:
-villain runs about 20/10, and raises mostly TT+, AQ+
-I had been raising a lot at the table, but folding to a lot of 3-bets.. so I felt I needed to take a stand at some point
-my mistake is prob 4-betting THIS particular opp.. but as played.. now what? c/f? 4-bet size too big?
