Finnal table bubble boy!

[ZoolooZ]

In the past i was a big winning player at MTTs but for the past 6 months i have been getting the worst beats. I keep getting to the final table in the top 3 spots then busting out in 7th and up! I know i am playing good and just supper unlucky recently. Anyone have any tips as to how i can keep my moral up and not tilt my money off in the cash games. And is it very unusual to go through streaks like this?
