I tend to go on bad streaks during FTOPs and mini-FTOPs... as in I start steaming in general. I think it has to do with the hope/wish for a big win. I find that busting out of several bigger tourneys and sats without a cash is detrimental to my attitude.
I can't tell you what to do. Once I find myself on more or less permanent tilt, I scale back a lot and avoid the big tourneys for a bit. Back to grinding out small SNGs and cash games, making a big effort to get my mental state more balanced. I may not play at all for a bit, just to get my head straight.
