Hello Doctor, I Am A 69 Y/o Woman Who Had

Hello Doctor, I am a 69 y/o woman who had cancer in 2007 and lots of chemo and then was referred to the City of Hope where I had a Bone Marrow Transplant in 2008. I am now 7 years cancer free. However I use to weigh 118 to 123lbs and I am now 250 and hate it. I began gaining weight as I lost each family member. I ate my grief. Would you recommend one of the WLS? I am driven by sugar and carbs, have type 2 diabetes and also HBP and am on meds for each. Thanks JC
