I think you are focusing too much on these bad beats. Even if you have been bad beated a disproportional amount, you shouldn't focus on it. AS long as you get your money in the middle when you are ahead, you should be happy win or lose. That's a hard thing to do, but its something that, as a poker player, you need to learn to do.

Although it may not be a bad move at lower limits, Pushing with ak and QQ is risky just because the hands that will call you like AA KK Ak QQ dominate you or result in a coinflip.

Regardless, if you are always getting yourself into the situations that you posted above, you will win in the longterm.
