Losing chips

I thought I'd loosen up my play a little. It worked quite well for a while. I was sitting pretty with 2,000 chips. Then it all falls apart. I raise 300 chips with A8, someone goes all-in and I call. I lose to KQ. That leaves me with 1,100 chips. Next hand, I'm dealt QJ. I call for 100 chips, miss the flop and fold. Down to 1,000 chips. Next, I'm on BB with A7d. 2 limpers, so I go all-in. Button calls with KQ and I lose. Down to 200 chips. Next hand, I'm dealt 97o. I'm in SB, I go all-in. A 3-way pot. The flop comes 568. Great I thought, about to triple up. Unfortunately, BB has 97o too. I've 300 chips now. Next hand, I'm in the button and go all-in. BB shows 65o and wins. That's it. I'm out.
