Jennifer, hey there!
Don't dismiss this as a "petty" problem! There are always going to be big things going on in the world that will make us think our "real life" problems are petty or insignificant in comparison, but that doesn't mean it's not important!
Moving in general is stressful. Moving long distance is really stressful!

Wanting to move to someplace that is completely different from where you currently live with the added benefit of being closer to family and friends and WDW (and the ocean and our neat Florida climate!) and then finding out it might not be so, is disappointing. It's like getting to the top of the rollercoaster and then finding out there is no track at the bottom!
Just because the move to Tampa may not happen NOW doesn't mean it won't happen later! Sounds like you have a great relationship with your DH and I'm sure he'll be open to discussing this with you! If this job in the midwest is a good opportunity for him, just consider this move a detour for a few years. You can still have all the fun of finding a new place to live, painting it, decorating it, working in the yard, discovering new places to shop and (dare I say it?) eat!

It's all a matter of perspective. Don't think of Tampa as "never" just "not right now".
Sending you lots of hugs just because! I HOPE that things work out and you become a Floridian sooner than later, but if not, just make the most of where you are! It will be a new adventure and we will get to share it with you!
Consider this a learning process. You are learning how to deal with stress a different way. Instead of eating through it, you are learning how to sooth your stressful feelings in a healthier way!

Lots of great tips in this thread! You know we care and we are always here to lend a hand/shoulder!
