In a funk

Lately I haven't really felt like going out. All I have wanted to do is go home and watch movies or lie in bed. I haven't been sleeping that well. I'm tired all the time and have little motivation to do anything. I'm surprised I have been able to stay focus on my diet in this condition. It's the only thing I have been able to do with any kind of enthusiasm because it's working. (I've lost 10 lbs!) I told this to a couple of friends and they all ask if I'm depressed. I don't think so but then again I have never been depressed before so how would I know. I think I am just going through a little funk. I think in a way I have always been a little bit of a homebody. Last year, I started going out more then I usually did because my friends at work would go out. Since, Jeremy left we have only been out once since. I'm hoping I will get out of this funk soon. I miss my friends.
