Emotional rollercoaster

I had a RNY in 2003.  I lost 150 lbs.  I didn't have a lot of emotional changes.  I then gained 90 lbs back and decided that I was not going in the right direction so I had a band over my bypass.  To date I have lost 75 lbs and I LOVE having the band, but now I feel like I am having a mid life crisis.  I want to do everything, some of them not such a good idea.  I feel like the old me is warring with the new me and the constant battle is confusing and frustrating and quite frankly scary.  Anybody else dealing with this?
