AA utg 5 handed; any advice/comments??

[mtnpoker]

Hi everyone,

This is my first post on here and I need some advice/comments/analysis.

Situation: $1 45 pl sng on PS, down to 11 players, I'm on the 5 handed table under-the-gun with A [img]/images/graemlins/spade.gif[/img]A [img]/images/graemlins/diamond.gif[/img]; blinds 100/200 with 20 ante.
Chip counts starting with mine: 5410, 8900, 5900(button), 6575(sb), 7650(bb).

I raise to 800, sb and bb call.
Flop: 3 [img]/images/graemlins/club.gif[/img] J [img]/images/graemlins/club.gif[/img] K [img]/images/graemlins/spade.gif[/img]
SB moves all in, BB calls, and I call.
SB shows K [img]/images/graemlins/club.gif[/img] 4 [img]/images/graemlins/club.gif[/img] BB shows J [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/club.gif[/img]
Turn: 4 [img]/images/graemlins/spade.gif[/img] River: J [img]/images/graemlins/diamond.gif[/img]

BB wins with trip Jacks and I'm eliminated in 11th place.

Did I do anything wrong? My preflop raise of 4xbb? My call of two all-ins after flop?

What about their calls pre-flop?

I tend to steam after beats like this. On a side question, what can I do to not get so upset after beats like this? Any philosophies, or books about that?

Thanks,
