New here, well sort of -....

HI all!
I've been on this before but didn't use it to it's full advantage. I lost almost 40 lbs and have been somewhat stuck there. My kick in the butt was having some blood work done.....high cholesterol, pre-diabetic - eek! so my doctor has given me 3 months to make changes and try to reverse the numbers (or we discuss medication) so here I am again, 5'7 and 222. (I can't help but wonder what my numbers were before I lost that 40, yikes....)
would love some encouragement. my biggest downfall is motivation and will power. I'm like anyone else and don't like admitting I can't do something, but I think at 39 years old in this shape I've proven I'm not doing so well on my own.
trying to navigate around this site a bit more and hope to find some motivation buddies :)
