In a freeroll tournament I had 5410 in chips (twice the average stack - a fairly good position to cash).
HAND 1: 1st to act preflop with [8

HAND 2(the next hand): in big blind preflop with [J

] and rivered me - I'm done
My Questions:
1) Are these just bad beats?
2) Are other players just donks (am I a donk also)
3) Should I have played these hands differently
-eg. fold after reraise in both hands
-eg. raise on flop in hand 1
I am tempted to give up freerolls altogether.
