It's very unlikely that you suddenly became a losing player after 35k hands with > 2 BB/100, so you should assume it's variance doing what variance does. Pouring over your stats looking for small leaks probably won't help you at all.

When variance dishes out a downswing, it's all in your mind. You need to remember that the order of losses and wins doesn't matter. How you are doing right now doesn't matter, what matters is your average win rate.

You've experienced a lot more more losses than wins for the last 10k hands, so what? Keep playing your best and the wins will come and your results will take care of themselves. Downswings makes you doubt your abilities, but learn to rise above this.

Becoming indifferent to short term results is not an easy process, but keep working on it and you'll get better at it.
