{{{Tep}}} Being worried about a person undergoing heart surgery is very tiring! Having a migraine sucks full stop. You are not a dick.
Wow, Jess, that sounds wonderful!
All of that!
Also, what's especially exhausting to me is coming down after the adrenaline of the worrying, even if you didn't realize you were full of adrenaline, suddenly it's gone and you are wiped out.
