I truly empathize with you. My fiancé committed suicide in Jan. 2007.
For me,
EFT was probably the most significant factor in my recovery. It is basically accupressure + cognitive therapy, rolled into one. Many people use EFT on their own, but I worked with an experienced practitioner. I strongly feel that an experienced practitioner is vital when dealing with complex issues.
It took me about 4-5 months of EFT to "get over" the suicide. As you mentioned, suicide brings out the most negative aspects of ourselves, and then paints it even blacker with the suicide baggage. It took me another 6 months of EFT to start chipping away at the black paint and re-program myself.
At the moment, I am broke, homeless (I have slept on my cousin's couch for over a year), and recently broke up with my new bf. And yet, I'm happy to report that I am in a happier place today than I was even before the suicide (when I had "everything").
P.S. Don't discount your therapy. It helped you get to a certain point in your recovery. Every step counts.
