I am new here and I'm REALLY sorry if this is discussed a lot, but I didn't do very well when I tried to search for it. 
I am having a lot of trouble with people who have found out I'm starting Slimming World and keep saying "You don't need to lose weight" or "But you're not fat".
When I say to them that yes, I am overweight (I weigh 12st 7lbs and am 5'6") they say "BMI is a load of rubbish" and I know they're just doing it because they think it's what I want to hear but it REALLY isn't.
I have to wear a size 16/18 in trousers/jeans and nobody actually believes me that I do. I think I must just choose flattering clothes. Everyone assumes I'm a size 12.
In reality this sounds flattering and nice and everything, but I know (realistically) I am overweight, I look okay in clothes but without clothes is quite another matter and I can't wear skimpy/tight-fitting clothes. I think I must just have Gok Wan skills and dress well for my shape!
What is the best thing to say to people who say I shouldn't try to lose weight? I've been unhappy with my weight since I was about 11 years old so surely that's reason enough?
I would just like some support on this journey and would like my friends to share my successes with me but they'll probably freak out if I say I'm happy to have lost 1lb or something. 
Any advice?
