More Thoughts on Health and Weight

I have continued to think about this difficulty (unfortunately, think is all I have managed to do) with making consistent choices in diet and exercise regimens.  I don't know if anyone else has struggled in this way, but I also have been dealing with some undiagnosed health issues that are kind of stressing me out.  I'm going to an endocrinologist now, and he's looking for specific clues...  So, I'm all freaked out about what he might find...does anyone else eat when they are stressed?  The problem is, being overweight probably just makes the existing issues worse...it's awful...when I have something yummy at my fingertips, I'm seized with a frantic desire to grab right now, because someone might eat it later and I'll miss my chance!  Eeeeek!  What's wrong with me? 
Recently the Lord has healed my heart concerning a relationship where I was sinking under bitterness and resentment...and I know for a fact that He took my heart of stone and gave me a heart of flesh...So how does the Lord play into what and how we eat and the lifestyle we live?  I want to be healthy...I've been healthier...and felt better...but there are times when knowing that I have to endure a million "no's" over the course of 6+months in order to gain victory, makes me just not want to try...it feels so depriving...like I'm losing some kind of source of joy or fulfillment...that's never quite done or full(no pun intended)...
Along that topic...I wonder if a lot of mothers (especially of small children) end up using food to "feel good"...since we rarely can do much of what we used to do to "feel good"...but I also wonder, then, if the ways in which we used to "feel good" weren't all that profitable...in the long run...if I take the time to dwell on it, my clean kitchen makes me feel good, but not in the same way drawing or painting does...I spent a LOT of time drawing and painting as a young person...now, I spend a lot of time cleaning my kitchen...but unfortunately, it tends to be messier than cleaner....I rarely draw or paint...only sew occasionally...food is a "feel good" thing, that happens pretty much right now...or whenever I want to...whereas the other things happen rarely...but lots of other things happen, like tons of laundry...scads of dishes...piles of swept up dirt...mopped floors and so on...but none of those are "feel good" things...and you know they will be there later today to do again and again... And I come full circle...because what I think the Lord is trying to show me is how many treasures on earth I have sought...and sunk to looking to foods for delight...because no matter how well I draw or paint...no matter how delish my baking...or how tidy my house...they are all made of things that will NOT stand the test of eternity...only HE will...and what prevents me from filling up on Him?  Oh, lots of things...distractions...kids...tasks...my unfaithful heart...the fact that He wants all of me...and that sounds so hard...and total and complete...my heart, over the years, has not developed a taste for Him...no...too busy developing a taste for the things (even good things) of this world...things that really have no lasting significance...my drawings will fade...my paintings will never be Ver Meer...my ability to enjoy food will fade...food itself won't usher me into eternity...but He will... 
I find it ironic that while I have such strong convictions on some things, others are harder to put backbone into...in high school, my stance for purity before marriage was VERY strong...my stance against things like smoking and drinking and drug use was also immovable....but when it comes to food?  Chocolate and the like?   I turn into a jellyfish...But what to do?  Can't turn nun and disappear away from temptation for 6 months...Can't make a resolve...No more cooking!  I have to...My family needs me to feed them...Just don't know how to handle the next 6 months or so and actually achieve victory...it has to come choice by choice, decision by decision, purchase by purchase...sigh...I think I'll go cry...
