Left my Iphone home today

I am a complete wreck when I leave my Iphone home. I literally cannot function here at work. What in the world is wrong with me. Has anyone experienced leaving their Iphone or any cell phone home for that matter. I really cannot get through this day without it. Does that mean I am addicted...could be. Everything I do relies on me have my IPhone in my purse. From my calendar, to the lovely voicemail that allows you to keep your minutes, to all of the wonderful apps. I don't know if I can go on without it. I may have to travel the 30 miles on my lunch break to go get it. Sad...but true!
