Why doesn't our body come with an owner's manual?

I'm still having a big issue with writer's block, this sentence alone took me five six days to write. The past six or so weeks have been a roller coaster with out of whack hormones and stress induced depression. Every morning I wake up with determination to get back on track with my healthy eating and by mid afternoon it goes down hill very quickly. If only our bodies would come with an owner's manual to help combat these tough times.

Honestly, I'm amazed that I've only gained about 8 pounds back over the past month. Not that I'm proud of that but, with the amount of unhealthy food I've consumed, I should have put on 20lbs.  I've had countless doctor's appointments and think that I'm on the path to recovery. The problem is I'm not there yet and I need to overcome the urges I have to eat junk food in order to create an imaginary happiness.

Where do I go from here?

1) Continue teaching classes at the Y and start back up with running
2) Begin regularly blogging and journaling about my progress to hold myself accountable
3) Faithfully record my food and exercise on Myfitnesspal as well as in the accountability group I'm in on FB
4) Redo body measurements, find out my body fat %, and take a "before" picture
5) Daily meditation to help reduce stress
6) Begin every day with prayer, reevaluating my goals/ looking over my vision board
7) Pray for strength, will power, and faith & knowledge that God is in charge and that I must trust in Him!
