Can I have a hand hold up please?

Lost about $150 this weekend in MTT's, SnGs, and cash games.....ALL on 2 and 3 outers

$20 SnG - Bubble time, I've got K 10 vs K 4 on a K 6 2 board. He bets, I raise all in, he calls.
4 hits the turn.

$30 MTT - I move all in with 2 pair jacks and tens on a 2 J 10 board, guy to my right calls with QJ. Queen on river

.5/1.00 NL - I've got AK and bet out 5 PF, one caller. Flop is AA4. He bets out $10, I put him all in for $40 more, he shows AQ. Queen on river.

$20 SnG - Down to 5. I've got 10 10 on the button and make pot bet. BB (Chip leader) calls. Flop is 2 5 J. I bet out 1/2 the pot, he min raises, I move all in, he calls. He's got 88. 8 on the turn.

Why does it come in streaks like this? I don't mind losing one every once in a while, but it comes in waves. This is really beating me down and I'm playing the circuit event in 10 days, not a good time to be in a bad frame of mind.

I may take some time off. I don't know......
