Experiences with long streaks of bad luck???

Hi all,
I'm wondering if other people have similar experiences as I do.
I've been playing online poker for quite some time (400+K hands) with some success, but on and off over many years (mostly PokerStars).
A few months ago I decided to start again with the goal of trying to go professional, preferring tournament play.
Though I have won several tournaments at the micro/small stakes, the toll has been quite high in the sense that I'm going through extremely long streaks of (absurd) bad luck.
I'm constantly analysing my game and I admit that in the past a lot of that "bad luck" was (at least partially) caused by my own mistakes. These "mistakes" have, however, seriously decreased. Unfortunately, the bad luck has not.
To give you some sense of what I'm talking about: I make a distinction between "normal bad luck" (board cards not going your way, villain constantly having or getting something better than you) and "ridiculous bad luck", the latter being when I am 80% or more favorite to win the hand on the turn, but somehow the villain beats me on the river.
In my estimation, 80-90% of the hands I play will fall into one of these 2 categories, while the "good runs" are limited to maybe 1-2%.
And this has been going on for the last 2 months (80+K hands), although I must say it seems to be more extreme at some poker sites then others.
Also, in the few live events I played I had a completely different feel about my luck (better).
Can anyone relate to this? Do you have similar experiences?
Thanks for your comments!
