I suppose it's a simple question that will beckon a simple answer to what is a serious problem for me. I just need reassurance on what is the best approach from here.

That old common wisdon: "Play while the game is good and you are playing well" applies here, even though your in SnG's.

If you're distracted, you're not playing well.
If you're tired, you're not playing well.
If you have a headache, you're not playing well.
If you're fearfull (of losing), you're not playing well.
If you're on tilt, you're not playing well.

If you're not playing well, get out of the game. It's just not any harder than that.
