I would like to know if anyone else has this problem. I'm on anti-depressants and have been for awhile. The thing is whenever I get sick, from either a cold or the flu, I also get really blue along with the other symptoms. Is it because of my ammune system, or hormones changing when I get sick or what is it? I was fine until I became sick. It's always this way.I'd appreciate your getting back to me. Thank you.
