Hey FlyingMan:
I love The Work, it's a terrific way to get to the root of what's really bugging you. I'm not sure how you arrived at your "turnaround statements," so it's hard to tell how effective they are.
But there is a free "hotline" you can call to do the Work with someone trained it:
The Work of Byron Katie - Do The Work Network - Byron Katie International Online Community
Also, you say that you've tried various methods to get over your ex-gf. This makes me think three things:
1) have you tried any of these methods with another person facilitating, or just on your own? It often makes the difference to do these self-help things in the presence of a compassionate person who can see things you may not be able to see.
Also, with EFT, watching the DVDs helped me understand the process better than just reading about it.
2) If you continue to look at it as "getting over your ex" I think you're going to remain stuck, because you're focussing on the negative.
Your girlfriend left you, that's the truth, but you're still the same person, whole and strong, that you were when she was there. So it's not her leaving that's hurting you, it's the painful story you're telling yourself on top of that, in addition to whatever old grief you may be feeling from previous hurts.
3) Breakups can often unleash old feelings of abandonment and helplessness that need to be healed. Maybe it'd be more effective to start looking at the older pain underneath the more current pain.
In other words, instead of trying to get over your ex-gf, you could look at it as healing and becoming independent and whole.
(And, yeah, sometimes having a rebound fling does make you feel better! I'm not going to knock that tried and true method, as long as you're not hurting the rebound girl.)
Sorry, this is rushed, I hope it makes sense.
