I need some psychological help..

Ive been going to the casino for quiet some time now,, and occasionally i come out a winner, my problem is, the suck outs.

I cant stand them, I sit down at the table play by the book, I play tight

then after 34 minutes of waiting i get Ac-Qc suited everyone limps to me on the button i raise 2-4x the big blinds.. i get 2 callers

the flop is 2h-Qs-7h, they check to me i bet the pot, one folds 1 calls,

Turn is 6c, he goes all in, I call, the river is a Kh,, I show my AQ, he flips over 9h,3h I loose all my money.

and this is how my night normally ends (every single time i loose all my money to a donkey suckout) Am i not mixing up my game inof and im raising to much and i playing to much(i play 2-3 days a week), I try to go home and say well Like the book says, over the long run I cant loose money playing Tight/Agrresive,, but then the reality that i lost 500$ a week sinks in.. and i feel like kicking stuff around my house, Then i say to my self OK im going back tommorow and making my money back.. SAME results loose my money to a suck out.

any advice or tips to deal with this kind of situation?
