That is a terrible feeling, and logic is no match for gut feelings. Can you break down into pieces the triggers for this- like what specifically does she do or not do that gives you this feeling? Could it be feelings about yourself you project onto her, could it be that you don't really like her right now, could it be that you do really like her and she really likes you, and you are pushing back against the connection? Rough sessions are the worst. Sorry it is struggle time, and I hope things get better.
