Do you know how you got the blister? I'm guessing it was from certain shoes or even certain socks with a seam that rubbed. Whatever it was, do not try to use those again.
I think you are making good progress.
Are you eating
enough breakfast? Even people who need to lose a lot of weight should probably not restrict calories down to a starvation level. You have probably heard that causes your system to slow metabolism further in effort to save you from death. and afterward it becomes harder and harder to lose weight--not to mention easier to gain weight if you do increase your calorie intake. I think that I personally have experienced that.
Now I think the slowly, but surely method of gradually cutting back calories is better. Plus, it really does make improved eating a habit rather than a give-it-your-all project. Projects come to an end. Appropriate eating will need to continue forever.
