Andrea, it's hard when things start to unravel...to try to catch up with the aftermath. Sounds like new beginnings are definitely in order for you! Re-evaluating YOUR goals. What do YOU want out of this? And WHY do you want it? Make your goals achieveable. Something at the end of the first week you can look at and say "YES, I DID THAT!" If it's work out for 5 min's every other day...then great! But set the goal, and then make it such a firm commitment to you - that come heck or whatever...you will do it!
Once, you have made it thru the first week...repeat goal #1, and add a second small goal. So at the end of week two you should have 2 Big Successes!!! Then, repeat goals, 1 & 2, and add a 3rd.
Sit with pen and paper and chart these out. From food goals, to water, to exercise, to prayer, to time w/ family and loved pets, to whatever. Each week adding the next goal to the previous weeks ... over time you will rebuild great habits to successfully reaching small goals!
It doesn't matter if your goal is to lose one pound a week. That is a great and very doable goal! Don't think months down the road. Think about this week. How you can help yourself to reach that one pound loss.
Still thinking of you often, and praying for your husband's healing! Much Love.
