Bless your heart. I am doing the same thing. Hot, cold, moody, worry. Everything is irrational. I have suffered so much from worry and anxiety with this mess, but really everything about my life is more secure than ever before. So why am I in such a fluster all the time? I've cried over worrying if something happens to me. I've cried because my kids are so good.
And no, I can't hide every hother flash. The milder ones, sure! But the ones where sweat is pouring off my face and I might burst into flames or faint and I'm reaching for my water bottle which I gulp down in two gulps. No, can't hide those. If people didn't notice on their own, they're going to notice because I'm repeating "Is it hot in here? Why is it so hot? I'm dying from this heat!" My glasses steam up from them. And then a few minutes later I'm freezing. Fun stuff.
