Day 2 of diet..

My husband and I got married a year and a half ago over that course of time we've both gained some weight I've gained 70 pounds to be exact!! It sounds stupid but I didn't want to accept it i would try to hide it in loose dresses and now I'm done I want to get this weight off I don't feel like the same woman!! I was 140 when I got married now I'm 210.. I'm trying to diet healthy I just hope it don't take me over a year to get back to my old self!!
