Today was a lovely day...75, low humidity.....So why do I feel so lousy..

I think it's not just the heat or the cold...I think it's the constant changing, back and forth, weather, that's killing me.
I'm so sorry, you all are suffering and not able to simply live your lives to the fullest, right now.....It sucks!!!
I'm going to bed early tonight, as I just don't even have the energy to have fun. If the weather stays the same tomorrow, maybe I'll feel better.
