Welcome to Spark People and to the HBP team! You'll find all the tools, information and community support here that you need to achieve you goals -- but in the end, of course, you are the one that has to do the "work." I put that in quotes, because it really shouldn't feel like a deprivation or torture type of thing, but you do need to kind of get your mind around the idea that changes need to be made in your lifestyle...
First, I would suggest writing down your goals and your reasons for wanting to achieve them. You want to lose weight -- and even took the measure of having surgery to accomplish that -- but you need to define why you want that. I have a number of reasons for doing so, but perhaps my strangest one is that, having been a medical transcriptionist for many years and repeatedly seeing this in the dictation, I don't want to be the patient that has surgery and the surgeon puts in the op note that he had to use extra-long instruments to get through the fat layer!
My point is, you need to figure out what motivates YOU, not what you think should motivate you, or what motivates someone else. Then write it down and re-read it as often as necessary to keep focused on it.
If exercise is painful, start by focusing on your diet. Use the nutrition tracker here to not only keep track of the calories, but to balance out your nutrients -- the daily feedback will tell you if you are getting too much fat, too little protein, etc. Enter everything you eat, every day -- if you don't, the only one it affects is you and your journey to success.
Check in here (and on your other teams) often, to let us know how you are doing -- and you need help, or just a word of encouragement, just ask -- we are here for you!
