hit rock bottom!!

Ok so we've all been there, where we see that really big person and that evil little voice in our heads say I'll never get there... Well I I've gotten there! I started a new job at a hospital where they premote healthy living and staying active so I jumped on... only thing is it's kinda got me depressed! I weighed in at 266 and a BMI of 43%!!!! I never thought I was that big! It kills me that I have let my self go! So here it is: I am at rock bottom! No where to go but up from here... I am just hoping I can do this and not give up. I don't want to wait until I am like one of my patients, and have a world full of issues cause I didn't do anything about it now while im 22.
