Finding Myself

Usually I feel like I'm living two different lives- but lately, I feel like I've been living like 4 of them. Obviously, there's the weight-obsessed/ where can I find a bathroom life that only people who know me as "Smaller" can either know about or understand. Then there's the workaholic - where at work I'm known as the super-organized super-all together person who has everything under control at all times. Then, at home, when it's just me and the hubby, I'm the lazy watch-tv girl. At home, when we have friends over, I'm the Martha Stewart of the bunch. Oh, and lets not forget the golden granddaughter, successful daughter, straight-A student, ect ect. I feel like the all the different personalities I've created for myself are not crushing me.
I really think that's one of the reasons I haven't been on here as much lately, it's just another person that I sometimes don't have time to be.
Today, I woke up and I just knew I couldn't get through work today. Long story short, I called in sick so that I could just sit back and relax. The problem is, when you play all of these different roles- I'm not sure who I am when I'm by myself.
