Donks will give you bad beats: AA, even if it the greateast hand preflop, gets cracked by trash hands all the time. I can understand your frustration, but remember that if you get all your money in the middle with a donk holding such premium holdings, you'll be a very huge favorite to win in the long run (thus making more money for you).
Also, something I've learned, people might not do these things in a live home game (and at least you can choose who you play with, thus increasing the skill>luck ratio). So, find some people to play with, hone your skills, build your bankroll on the internet and then move up once comfortable. But, alas, donkish plays and luckboxes are there even at the highest stakes and levels (Dimitri Nobles and Jamie Gold come to mind).
