It took me quite a few trial runs, myself, before l finally was able to make that mind/body connection needed to make it stick. Its been over 2 years that I've maintained, so I know it's possible, even after years of being a major yo-yo.
The most important thing a person needs to do, and you've already done it, is to get right back up! It's not easy to admit, to yourself or others, that you're right back at the starting point again...but it's a road a lot of us have traveled on, so all the peaks and valleys are very well known and shared.
So, great job on getting back and working it, girl!! You'll do awesome!
