Kinda feeling blah, moody, and uninterested

I don't know if it's outside factors or hormonal issues due to the weight loss, but I've been feeling just... gah...

Weekends come and I don't want to go anywhere or do anything, yet I'm bored... I don't want to be at work... I sometimes feel irritable with hubby (okay, that's probably just him, lol).

I should be excited and happy about my weight loss -- and I AM -- but I've also had this undertonee in my life that I can't figure out.

I take an antidepressant, but this is working its way around that.
