Not a strategy question.
It seems like you're looking to find out how much of your losing streak is running bad, and how much of it is playing bad. The answer is, you can't really know *exactly* how much of each it is. What you can do, is ask the other kinds of questions you've been asking, and hopefully improve your play.
I dunno if anyone else has said this to you specifically, but it is said often and with good reason: bumhunt! Find the fishiest table, and play that. If you have three nights a week that a game is available, and one of them has mostly good players, *just don't play that night*. It's okay--poker will still be there on the other nights. Better to skip a night you'd probably lose, than to play because you "need hours".
