Its so aggravating when you know you're doing everything right, but the scale is still in denial.
It must have been so satisfying to get an size 8 dress. I'm around the same place as you in the pants department. Some 11/12's no longer fit 100%, but 10's don't always fit, either. I found one pair of tens that fit quite well, so I bought them a little while ago. They are just a tad snugger than I want them, but I find it so deceiving since most of the pants I have are looser than they should be. I'm kinda getting used to low slung loose pants, so its hard to go back to regular fitting pants. LOL.
You're doing good, hon. I'd love to play volleyball, but I haven't played since high school gym class. LOL. If I get in better shape, I might just get up the courage to find some beer-league sport to play in. That would be a major stretch for me as it is!
