it's the overall sense of feeling older that well kind of bothers me
Yep I have that feeling too, started feeling it in the last few months (I turned 35 last month). I think finding a couple of grey hairs hasn't helped And I definitely can't eat like I used to without putting on some flab. And that flab is WAY harder to shift now.
DH wisely says 'well you can't change your age so just go with it' lol.

btw I think your gorgeous and you look years younger that what you are!!
