Gastric Bypass Surgery Support Group
Gastric bypass (GBP) is any of a group of similar operative procedures used to treat morbid obesity, a condition which arises from severe accumulation of excess weight in the form of fatty tissue, and the health problems ("co-morbidities") which result. If you are considering gastric bypass or have had it, join the community where we share our experiences and find support.

You probably already know this, but t's totally normal to be a bit scared at this point. I'm impressed with how thorough you've been in your planning - - - did you think of setting up a surgery buddy? (someone from here at DS you can text/call so they can update us?)
Can't wait to celebrate your journey towards being the healthiest version of you!

Regarding intense emotions, I'd like to suggest that you get on YouTube and search either EFT (emotional freedom technique) or tapping. Same time, different terms. The technique is based on accupressure sites on the upper torso and head. Many of us have discovered that tapping on those points when in the midst of a strong emotion works to relieve the emotional pressure. I know, weird. But it works, so it's in my bag of tricks. It might help you as well. :)
my GP gave me another certificate, which means i will get paid for my recovery, yay. less than 24 hours to go now but who is counting lol
