Hi Jamie &
How wonderful! You've lost an amazing amount of weight.
I, too, am following WW

You might enjoy the WW section under Diet Central. There are also groups for people around certain ages, there's also the 100 lb club that you might like seeing as you began this journey looking to lose about 100 lbs
I hope you're able to find some tips about moving through a plateau. Stick with it, regardless! It's so worth it.
Best of success!!!
