I obsessed about turning 30 the entire year I was 29. By the time I actually turned 30, it was no big deal! LOL
35 and 40 were pretty horrible for awhile, but once you get used to it, it's not so bad. I spent my 30s undoing the damage of my 20s, and so far all 1.9 years of my 40s have been remarkably good. I appreciate the life experience, just wish it hadn't come at such a price.
BTW, for my 30th, my mom got me a card that said, "Admitting you're 30 takes courage. And 5 or 6 years."

Which turned out to be very true for me! Maybe if you just eeeeease into it like that it won't be so bad.
