I too have arthritis (although I'm lucky not to have it as severely as you do), am a grandmother, and love my dog. I work full time at the City of New York - in downtown Manhattan. I went back to school in my late 30's when I found I couldn't stand on my feet all day. So - I really recommend it. It is alwo fun and some lots of folks are intimidated at first - I found many student friends. I am working on the 50 pounds I need to lose. The problem for me and diets like Sonoma is that I get the book, get excited about it, don't get to the store one day and blow it. What works for me is to cook stuff on Sunday afternoons. I make a huge salad and bag it up for the week, roast a chicken or two - just make everything easy and simple. Fortunately it's just my husband and I, now, so we don't have kids wanting to order in pizza, etc. I walk walk walk, but don't do anything else. I have good shoes to keep my joints from rebelling and I take it as slowly as I need to.
Happy to be your buddy. I've been working on my weight since January 9th. 215 at that time and I'm down to 196. I also use FitDay to track what I eat. It really helped me get my head around what I was eating.
Anyway - good luck. I think the only thing is to keep on keeping on - It's a struggle and I never really believe anyone who says they have the answer. Sometimes I can move more and sometimes I can eat less and sometimes both and somethimes neither
Laughing is good, though, even if it's just at my fat fanny.
I've never volunteered to be a buddy before, so I don't know how it works, but I'm out here.
