Still trying to figure it all out

My downswing is ongoing. the last 3 months have gone as follows:

September - win $2212

October - win $58

November - lose  $477

Early in December I decided to take a week or so off from playing online  poker hoping this would refresh me and get me back to winning ways. Unfortunately it has made little difference as evidenced by my December month to date results:

12/15   - 31       0      0    - 31    - 61

Not too good. After my break I started playing again and had ONE day of positive results at Full Tilt, then continued losing money. The strange thing is I have been playing cash games on Full Tilt and winning.  For example I played on 4 tables low-stakes NL on 12/15 and ended up $71 in profit for about 2 hours work. But in the tournaments and SitNGos I continue to lose money.

Possibly the simplest reason is the lack of a winning mentality (or going on tilt). Maybe my continuing playing tournaments where I go deep and then losing around the bubble is causing me to make bad decisions. Or maybe my recent reading up on cash game play has somehow affected how I am playing tournaments.

I am hoping to figure this out and get back to positive ways.
