Sheski, I know about the gym phobia, had it myself in the beginning. All I can say is, you have to find a reason to be there for yourself. If you want to change your life, you have to pick something to change today. If you want that change to be exercise, then you either have to face the gym, or just start walking room to room in your house, buy yourself an elliptical, or whatever, but just pick one habit to work on and build from there.
What helped me at the start of this was to write down one goal at a time, in each of these 3 areas: food, water, exercise. For me, just one step at a time worked best, so I'd say, "okay, for September, I'll be giving up just cheese, I'll be drinking 3 bottles of water a day, and I'm going to walk for 10 minutes every morning." So, something like that, and I would just commit to those goals for as long as it took. So, it's not a lot of pressure, but it's an improvement over what I'd done before.
After a little while, when I felt like giving up cheese was no longer a struggle, and drinking 3 bottles of water was a habit easy to keep, and every day I just got up and did my 10 minute walk room to room in the house with my stereo cranked, well, I'd set another little goal to reach for, maybe I cut my usual mayo in half, I add another half bottle of water, and I walk 10 minutes and jog for 30 seconds at the end.
Whatever works for you, whatever you can do today, and take control of some small thing, do that. You don't have to go from out of control to super diet and exercise girl overnight, really, to be successful. I am the proof of that.
