Well there is good news and bad news.
Bad news first- you're sick.
Good news- everything else!! You are still down 2 pounds. You know what the gym is like and re-starting will be easier. You can turn around you last month overnight. You can be back to 6 pounds down by the end of the month. You have already decided on change by posting here. You just need to invest just a little time and you'll be back on top.
All of these things are on your side. It's just a matter of how you look at it. A short time ago I had a MAJOR food meltdown, and it took a little while to recover. I got right back to eating/exercising right, but the mental took some time.
Tomorrow when you wake, decide to only make good food choices, and go for a mile walk. These are goals that you should be able to hit. At the end of the day, relax, clear you mind, now ask yourself. "Do I like me better today or yesterday?" Do the same the next day.
Once you get pointed in the right direction ask yourself another question. "Was the downward spiral worth it?"
When your out of harms way, try to contemplate what started the whole thing. Then decide how to handle it next time.
Hope this helped, it's what I used to get me going again.
