take your list, tell them you are serious, tell them being over weight is destroying your life in every aspect both physically and mentally, tell them you know its not a magic cure and you are willing to work with wls 100% to achieve what you have craved for, for many years, tell them if you cant loose the weight and keep it off long term after all the diets you have tried previously in your life then wls is your last chance to turn things around, tell them it will cost the nhs more in the long run for the weight related illnesses that come as you get older, than it will cost for wls.
if you still get a negitive response move on to the next gp NEVER give up fighting them, i didnt, the more you nagg them the more they take you seriously.
i wish you good luck hun, if things dont go your way tomorrow, u must keep up the fight !
