How to handle bad luck, cold streak, and bad players.

I usually play homegames and online a lot and in the past after making $1000 in a week, I've lost about 400 of that to horrible sick beats. One was a runner runner inside straight someone drew to after I kept reraising with a set, anothethis guy called me with K8 when i had A10. I pushed all in on purpose so he would not call screwing me over. I knew he had a bad hand because he raised the minimum, and I my all in was 5/6 of his stack. He thought it was good because he won with it at a casino, and doesnt see the difference between going all in with pocket 8's and K8 if 8's would still win. I kept having the best hand preflop and lose, ex KQ loses to KJ, AK loses to 10 7 of all hands! I know these people suck and are just going to be giving back their money in the long run, but how do I handle this? btw, K8 hit runner runner 8's to beat my pair of aces.
