Hi There!
It's great that you are making gradual changes. If you're concerned about your risk of diabetes, I would definitely speak to your doctor about it (and the sweet breath is also a concern). I know that I struggled with pcos for years because doctors only focused on my weight. I really had to learn to take up for myself!
And good for your for picking yourself up
I've definitely been there and I found that once I started taking steps to take care of myself, other aspects of my life began to fall into place.
You said you were starting to wear your pedometer... how many steps have you been getting? I try to aim for 10k a day, which is recommended for optimum health. At first I didn't think that sounded like much, but some days it's a lot harder than it looks
