This could be a blessing in disguise. The various surgeries should really be a last choice option, as the long-term side effects can be pretty crummy (ulcers, 'dumping'/vomiting, nutritional deficiencies and related problems like osteopenia/osteoporosis, iron deficiencies, etc).

Becoming more knowledgeable about nutrition (and working with a nutritionist), as well as trying to stay active. Walking every day (set times/levels) and doing other activities can make a big difference. Gyms can be helpful, though may be expensive...especially starting out.

Be careful of fad diets, as 95% of diets fail. (Barbara Cohen, Ph.D., "The Psychology of Ideal Body Image as an Oppressive Force in the Lives of Women," 1984). What works.....old fashioned proper nutrition + regular exercise. A lifestyle change is needed, not a diet. I hope you can find something that works for you. Best of luck.
