Poker question?

Hello,

I play a lot of home games with my friends. i dont mean to sound conceided, but i am playing on a whole different level than some of them. Lately it seems like no matter how i play i lose with an amazing string of bad luck. I can play every hand perfect and everytime on the river i will get screwed. When this happens i generally go on tilt, and end up losing more and more even though i continue to play perfect. i will pre-flop raise with excellent hands just to get beat by someone who played something awful pre-flop. i could have AK suited and bet 5x the blind and will get called by something like 84 offsuit and end up losing to 2 pair or trips. and lately this has happened literally every hand i've played. I guess my question is how do i overcome such bad luck? i know sometimes poker is 90% skill and 10% luck and sometimes its 90% luck and 10% skill, but latly it seems like its 100% luck for everyone else. Any suggestions on how i can possibly turn this around would be great.
