2Pair on drawy board vs river all-in

I think it is close. But this is NL2 where I think players don't raise as a bluff that often, especially OTT. Because I suspect his turn raise was already quite strong and now some more draws complete, I think you can make that fold.
But this is just based on my read on the player pool at lower limits and my gut feeling. Some others might think that villain will have bluffs often enough and we should call, and that is totally fine. In the end, it is up to you to decide how you think most of the guys play here

I just lose my stack on turn here (meaning jamming for value)

Well they can have it here or not...as everywhere else, too...saw some bluffs but mainly they play pretty honest. So I think the fold is fine but wasn't really sure about it

Turn raise plus river bet - just fold that river and move on.

My population read is that players at NL2 don't bluff raise turn. Sometimes you can find some crazy guy who bluffs on that spot, but generally these movements are quite strong. On the river I think it's an easy fold.
