Stress and weight loss

Life has recently thrown me quite a bit of curve balls that has impacted routine and my mental state.  Before I thought that I was an emotional eater,  but have quickly realized that is not the case...  I do quite the opposite, not eat enough!
So,  on the scale it looks like I did great this past week by losing 4.6lbs, but in reality it wasn't done in the best manner, therefore I'm not too sure if it will stick. I'm hoping I can really stay on plan this week and move forward on a better note. I don't want to get too excited,  but as of right now, my total loss is at 28.8lbs... Kinda crazy to think about!
