Hi there
You have taken a step in the right direction just being here and getting everything off your chest, so don't worry about how long your intro was.
I think you can definitely lose 10lb 10 times, and that's a really great way to look at things. I've used Wii fit in the past, and I found it a really fun way to tone up, so maybe bump it up to 30mins a day to lose weight a bit faster and feel more energised?
Good luck with everything! x
