Welcome! I'm 25 as well and would like a buddy. I'm 5'2", started at 162, down to 141 after 2 months on FitDay, but would still like to get down to 115-120.
Anytime you need a reminder to stick with it, I'll be here to help ya out!
My biggest weakness is all or nothing thinking - so if I mess up once, I feel like I should just give up. I'll need reminders that there are shades of grey in life, and one mistake doesn't mean complete failure and permission to give up!
Good luck and have a great day...
