Hello Jillian! You will definitely find a lot of great support here, whether you need answers to questions or just morale support! I started my weight loss journey a pound heavier than yourself (221lbs) and I'm an inch taller, so we are very close in size!
It sounds like you have a great plan in mind with some time between all the changes, so it shouldn't get too overwhelming. A quote I love to share (and I found it here on 3FC) is "if you stumble while climbing up a mountain, are you just going to throw yourself off? No, you're going to adjust and keep climbing." Essentially it means that if you do make a mistake, don't beat yourself up over it! Just make your next choice something back on track, and you will be successful!
