Downswing or just playing bad?

lost a massive 1800 dollar pot on a draw, I had basically a open ended straight draw, and diamond flush draw on the turn. Decided to reraise it all in and poof, no help on river. Wont waste your time on specifics, that the nitty gritty of it. The game was 3-5 NL at the Tulalip Casino, it also doesnt help my mood that I oveheard some asshole say well there goes the money. I have had 4 straight losing sessions now, which is just not good for the savings account as well as the, psyche. Really need to think about my approach to poker and decide if its time to change up a few things.

Also just read about SWAT team invading the hotel in Manila, should be interesting.
