Thanks for the responses. It is interesting to hear your thoughts and experiences. I think it might be for me a combination of putting on a front, being in somewhat better physical health than I have been in the past due to some chronic health issues, and the fact that instead of being my usual tired, sad depressed self I have been having issues with mixed states and I think some hypomania so depending on when you see me I might seem really peppy, but also could be feeling awful inside. It's just strange how many people, even people I am pretty close to, started saying this to me recently. They seem so genuinely happy for me, and I am like I almost checked myself into a hospital a month ago. Then I wonder if I just am making everything up in my head.
