Do the INTERNAL work first, and don't stop. Counseling, books, support groups. Do whatever you need to so that you are in a healthy place mentally and emotionally BEFORE surgery and then keep going because you WILL need it after. I did a ton of work before surgery and felt like I was in a really good place, but I didn't keep up with most of it post-op and really struggled for a while. The hormonal changes, body changes, and lifestyle changes all add up and suddenly I didn't recognize myself or my life anymore. this is a lifelong process, you will be a WLS patient for the rest of your life, and making sure you are taking care of your WHOLE self is so, so important.
