not doing well hu

I believe I dropped another 3 buy ins today playing .5/1 hu. I wish I could say it was just variance, but I am not sure I played entirely well. I don't have the HHs, because I forgot to click the save HHs option on FTP. I emailed FTP though and hope they can send them to me.
It's possible I was a bit tired today during my game and I probably shouldn't have played given that, I just felt like playing.
I am also down 1.5 buy ins on nl200, but I think I played well 6 max. Hu I was outkicked every time I showed down a made hand and alot of my bluffs werer getting called. For example I flopped a gutshot with 67s in a 3 bet pot on 34Ar and after villain cbets and I make it 3.5x his bet he calls oop and shows down 99. Later on in a 3 bet pot I reraise him with ajs. The flop comes down 252, but I still decide to cbet, figuring I can fold out a lot of overcards. He calls and the turn is q. I two barrel and villain shoves. That's kinda how all the session went. After I stacked off with AJs 3 bet on AK7 rainbow vs 77 I called it a session.
I guess the variance is higher hu, I am on a 6bi downswing so far and I think I am like down 3 bis overall hu for the month. The variance seems standard, but I am not confident enough in my game yet to leave it at that. I'll continue to play the 5k hands challenge though and I hope I can comeback from my poor run. I am pretty sure I have an edge on the opponents I am playing.
Interestingly enough, two people quit me today saying that I was playing too tight. It doesn't feel as though I am folding too many hands. I guess I have to agree with them though when they say I wasn't playing many at the time.
