Vanessa I think you've done really well considering the long path that you've come. You've got a few factors there that would have caused anyone to do the same, we're human after all.
Dust yourself off, and get right back on track. Good on you for making it so far, I wish I can be like you, I have a similar amount to lose!
I cracked the 90kg mark for the first time in two years, I'm happy!!
