Hi! New here - American in the UK

Hi there. I'm new to MFP and I like it because, as an American in the UK, it's hard to find a weight loss site that covers both American and UK food. This site so far seems to be doing that.
I'm 48, Type II diabetic and I've always been overweight - I was born overweight :-) I currently weight 200 pounds. I'm not into fad diets and I believe that the only way to crack this thing is through proper eating and exercise. My biggest problem is that I have not been able to go below 190 pounds in my adult life EVER. So I'm shooting for 180 and hoping for the best. If I can get there and maintain it, then I might try for more.
The thing that is really motivating me is that I'm an older mom. I am 48 with a 5.5. year old daughter. I worry that I won't be here for her when she's a young adult if I don't take care of myself now. And that is motivation indeed!
Are there any other US expats/older moms who might want to be 'friends' for inspiration and support?
