I can't imagine the stress of dealing with a child with cancer.
I'm so glad she is better now.
Now is the time refocus on you. You know this.
I think you need to break it back down to the baby steps -- you've been there before, we all have right?
First off, congratulations on surviving what must have been an incredibly stressful situation. You did it! You, all by yourself.
Congratulate yourself for that.
Now, first things first. You can't tackle the next round of life renovations unless you're healthy.
Put all that other crap (house fixing, finding a new guy, figuring out where to live next) on the back burner and start with weight loss. Get your diet sorted out -- go online and google Jillian Michaels, the hellion who runs 1/3 of Biggest Loser.
Get a workout plan happening -- go out and walk, ride a bike, do yoga, jazzercise, zoomba, whatever makes you feel good and whatever you can manage.
Do this every day.
If you're stress eating, taper off and start eating well, fuel your body for the tasks ahead.
Give yourself 90 days to just focus on this.
I bet by the time that 90 days rolls by, you will be in better shape to start figuring out the rest of it.
In the meantime make yourself a priority. And try not to stress about tomorrow. Just do this one day at a time, set some goals and work toward them.
And post here about your progress.
Big hugs, you can do this.
