Need help letting go

[Demana]

I misplayed a hand the other day and it is just killing me. I can't let it go and it is affecting all of my poker decisions because I keep railing on myself for being so weak.

The situation was this:

I was at a NL ring game.
$2/5 blinds

The table was loose and at least half the people raised preflop with garbage.

I was UTG with A[img]/images/graemlins/heart.gif[/img]K[img]/images/graemlins/heart.gif[/img]
I limped, looking to re-raise and isolate.

UTG+1 (who was new to the table, hence no read) makes it 30, CO calls (he called raises with just about anything), and I, in a total moment of weakness, just call.

I then misplay the flop by not folding, set up the turn for a steal on the river, and then wuss out on the river, costing myself 2/3 of my stack.

AND I CAN'T LET GO OF BEING SUCH A WUSS.

In hindsight, I should have raised to 3 or 4 xBB myself, rather than limp reraising, but that has done nothing for helping me get over this.

This is the first time that I haven't been able to let go of a hand for this long. At the heart of the matter, I am berating myself for being weak when I set up the play how I wanted and then not following through.
