Hi Laura, welcome!
Your story is quite similar to mine, although I am sadly 3 inches shorter!
I'm 25 in September.
You sound like you know what you're doing and have a plan all worked out, so kudos to you for that! Having a goal to strive for is epic too. When are you hoping to go to Florida?
I also have the same desires as you - to be able to buy in a high street store like New Look or Select!
I've come down from a 28 to a 22 so far. Once I get to a 16/18 I'm going to be such a fashionista...!
I'm also really picky and can't eat salad. At least not proper salad. I do a "Tibbles" salad which is lettuce, scrambled egg, chicken and baked beans.
So I totally know where you're coming from. I've started ordering from the childrens' menu when I eat out instead of opting for salad. Smaller portions but of more awesome food. I may as well enjoy what I'm eating right?
Best of luck and super hugs to you!
