I hope you get to feeling better soon!
I have to agree with all the previos postings. I've been there too (still working on it)! Here are the things that really helped me get started...and I really have just started. I have a dear friend at work that is just naturally thin. I watched her eat one day (I know, it sounds very odd, but we are REALLY good friends, so she didn't care). But, she NEVER finishes what's on her plate...even if it's a half a slice of cake.

So, I've kind of learned from her on my eating. Here are my things:
1. Start by just leaving one or two bites on your plate...slowly add the amount that you eat. You won't miss those two bites...I promise!
2. Learning real portions - have you heard of Lock and Locks on QVC? They are food containers...and they have a set that has containers that are 1 cup, 2 cup, and 3 cups. I was TOTALLY SHOCKED to see how little a 1 cup serving of something really was. But, when it comes to salad, I was shocked at how much could fit in a 3 cup container. This just really helped me see things clearer. In fact, I fix my cereal in the mornings with milk (in my lock and lock) and head to work. It is guaranteed not to spill...and so far it hasn't! Anyway...I love my lock and locks!
3. Start a journal on the wishes board. I did, and I can be 100% honest because I don't really "know" anyone on the boards. It feels so good to be totally honest about my weight, my food choses, and my exercise or lack of at times. No one judges here...most have been where we are, so they are just super supportive. My journal is listed in my signature...send me a note if you'd like help getting one started. It helps keep you accountable too!
4. Cut out one fast food meal to begin with. I notice that I tend to lose weight on the weeks that I eat at home more. You just don't know how many calories are going into those things...they add alot of things to make their food taste better.
5. Last thing I did was add little tiny bits of exercise into my routine. Park farther away in a parking lot just to walk a little more. I walk each isle at the grocery store just for the added steps. A pedometer has been very helpful for me too...I know when I'm not getting enough steps in.
You can SO do this!!! We are all here to support you in your efforts. If you love Disney like we do, set a goal trip and start working your way to it. This board is so supportive...you'll really find a "home" here.
Good luck!!! And let us know how you're doing!!!
