Chrome, I think Hap's and Corri's posts together hit the nail right on the head. Please read Hap's post over about 50 times.
You are clearly a very driven, achievement-oriented sort of guy. But all the while that you're driving yourself, you are afraid that you're becoming the overbearing bully that your dad was and second-guessing yourself.
The contrast between the self-effacing glob and the arrogant I-can-achieve-anything-I-set-my-mind-to SuperChrome has you bouncing back and forth between extremes. The arrogance of the SuperChrome is potentially just as damaging as the self-hate of the glob. The SuperChrome thinks he's uniquely flawed, prescribes meds for himself and then takes himself off them, turns his W into a bondage queen and then realizes he still doesn't have an EC with her.
My experience with anti-depressants (Paxil, Prozac, Zoloft, all at different times) is that they do not affect your sex DRIVE. What they affected, for me, was the ability to O. You just keep climbing that mountain, but never quite get there. If you do decide to try ADs again, please discuss with your C, go to a real doctor who knows you, and if you decide to stop, remember that SSRI's MUSt be tapered off gradually. Don't EVER stop them suddenly. There can be dire physical and mental consequences.
