Think positively , you are focussing on downswing so it is affecting the way you play even if you aren't realising it. Are you going to call the shortstacker's all in with your top pair top kicker/two pair or are you going to think "he's got me beat cos he's always got it".
I've changed my mindset, I've changed my strategy , and I've changed my typical opponents and dropped back down a level to recover my confidence.
I'm playing my moderate cards still, but in position , and for a limited pot. Before I'd flop 2 pair with moderate cards and bloat a pot and lose a big pot to a better two pair by the river. Lots of small pots add up to a nicely rising graph , several big losses hammer your graph and confidence.
