I have a history of sabotaging good and successful things in my life - my career and relationships have suffered greatly. I my own case this is related to 'performance anxiety'. I am so very afraid that I won't measure up I am convinced I will fail. I feel this way even when things are especially good in my life. This is where the sabotage comes up. I feel it is better to end things on my own terms rather than wait for that failure or disaster.

I have haad some therapy in this regard; both self-directed (I found a great book) and with a therapist. This was CBT (Cognative Behavior Therapy). I have a tool box of coping skills for the anxiety; in particular, the catastrophic thinking. Some of these coping mechanisms help during the moment, but the most helpful I find are those one's allowing me to deconstruct a difficult situation or event before I must enter it.
