Lap band surgery?

I am very depressed about my weight. I have tried weight watchers and food journals, diet meals.  I weigh 245 lbs and am 38bmi. I used to be a collegiate athlete.  I'm so discouraged all the time. I tried to be inspired to hike and went to buy boots... The salesperson said my feet were too wide to fit. I felt so sad.  I have considered getting lap band surgery to sort of jump start a new lifestyle. Has anyone had experience w/ this?
