First of all, great work making changing when your doctor said you needed to. That's not easy for a lot of people. It sounds like it was quite the journey to get the help you need, so double kudos for pushing on when you had to.
There is a section of this forum for losing weight with challenges (medical conditions, medications, etc.), which might be helpful to you. The whole site is a good source of information, though.
Good luck with your efforts, and
to the site! We're glad to have you here!
