Hi everyone, I'm really new

My name is Karen and I am 63 years young. I am a WeightWatchers lifetime member, over 100 lbs. ago, and haven't been able to get "with it" for years. My weight is going up, up, up, weekly. I am diabetic, with high blood pressure so have to get the weight off. I have never ever considered joining a blog, or anything, like it, but was reading a good book and it inspired me to start counting calories as a way of weight loss. I did Atkins for a long time until I found out I was allergic to eggs, cheese, cow's milk and anything made with it, etc. etc. so I had a hard time finding out what to eat. Anyway, here I am and I am happy to have committed myself to this site/blog etc. so I am sure that this will keep me on track, so to speak. I am a 'snowbird', so have a hard time figuring out what to do about joining a gym when I never know quite where or what I will be doing. Anyway, I have read lots of blogs and am impressed with how friendly everyone is and I hope that I will be able to add something as I go. Thanks for reading.
