I don't know what's wrong with me. I've been losing weight the tried and true way (diet + exercise, about 2 lbs a week) and it's been going good. I've gone from 225 to 206. I was going to the gym 3-4 times a week and eating well.
And then in the last week, I just feel completely apathetic. I'm eating things I shouldn't. I know before I ever stick it in my mouth I shouldn't do it. It's not that I'm eating a lot, but rather eating stuff that isn't good for me. Like today for lunch I had a lean buffalo burger (no cheese) on whole wheat which was good-- and then I popped open a can of mixed fruit in heavy HFCS. Why would I do that? I know that's not good for me. And I immediately felt physically crappy after that.
For the last 4 days, I haven't wanted to go to the gym, and I'm tired and my stomach is upset. I feel blue, but I don't suffer from clinical depression and I have no reason to be depressed. I was fine last week. Nothing has changed...I just feel blah. I was excited about my weight loss, and now I feel like I don't care. This is very sudden, and it's scaring me. I feel overwhelmed.
I could sure use some encouragement. What works for you when you hit a mental slump? What do you tell yourself? How do you motivate yourself? Any suggestions would be appreciated.
