Getting raised/checkraised on the river

[Dudd]

I'm in the midst of a 7k hand break even stretch and trying to find holes in my game. I think I make a crying call way too often on the river in these situations, as for whatever reason I feel very stubborn to lay hands down to raises or checkraises when I have any sort of a hand. While I don't think this is a huge leak (it took me five minutes going though my pokertracker database to find two hands that fit this criteria), whenever I make the play I feel dirty since I can't remember the last time I won in a situation like this, yet I can't get myself to throw the hand away. Anyways, in hand 1 the villian is a 16/7, but I felt that his preflop raise could have been an attempt to isolate against the fish who had already called. Villian in hand 2 is a total donk, with a 65/6 and a sub 1 aggressiveness factor.
