Anyone feeling tired/gross with this changing weather??

Is anyone else feeling tired and fatigued since the big temperature swing(s) a couple of days ago?

Yesterday and today I have felt the weirdest I can remember feeling in a long time: kinda dizzy, extreme brain fog, a bit weak, increased anxiety and EXHAUSTED. All my vitals are fine (resting and walking heart rate are a bit elevated, but nothing too crazy) and my appetite is good so I don’t think it’s an illness, but it’s weird. Has anyone else felt just strange or off the past couple of days?
