Lost 60lbs and all sexual confidence and desire

I know I am crazy, got a appointment with the Psycholigist next week. But it is really doing my head in. When I weighed 30kg/60lbs more I was much happier with my naked body and sex life. I love sex as much as I love food, but my love affair with food had to change or it was going to kill me so I got the bipass in Feb 2017 at the time I weighed 160kg and am 174cm/5’8” I was confident with both my naked body and my own sexiness. In fact one of my fears with the surgery (which btw want fantastically and highly recommend Mr A Cheng of Mater Brisbane to anyone) was I would loose weight and wouldn’t be as sexy any more. Yes crazy. But it seems that is exactly what has happened. My sex drive has dried up both literally and figuratively which really sucks but not in a good way. I hate my body and my ***** and myself. I just tried to use my hatichi and even that was no help. Please help my very 1st world excessively indulgant problem, that is driving me insane.
