When did I wake up old?

So this morning I got out of bed, happened to look in the mirror and scared myself have to death!!! I was like "Oh my God, who is that person in the mirror and who's skin is that?" My birthday is coming up RAPIDLY and I'll be 29 on the 29th of March. They call it the "Golden Birthday" when you turn your same age as your birth day....I call it...The anniversary of me turning 27 haha. The fact is, over the last 5 years, my skin started sagging, my eyes get puffy in the mornings and I don't function unless I have 2 cups of coffee in my system first......WHAT THE *%&$? What happened to being able to party like a rock star till 3 am Thursday, Friday, Saturday and Sunday nights and still be able to wake up chipper on Monday morning at 6:00am and feel GREAT!!!! Getting old sucks, Buck, my husband, takes age so easily. He turned 30 last August and didn't think it was a big deal, me...I'm actively looking for a shrink to get me through my last year of being a twenty-something.....I don't know why I fear the 30's but something about almost being 30 scares me to death. I honestly feel 23 still in my head,however now my thighs, skin, wrinkles and sagging boobs tell me I'm not 23 but still in my head I'm not ready to get old or "adult" age haha......Where did all the past 5-6 years go? Most of them were spent in a fast paced working, partying, sleeping it off, then starting that hamster wheel all over again the next week and before I knew it, the last 5 years have FLOWN by!!! I got married, bought a house in the suburbs, had a baby and it all feels like a blink of an eye. If the 20's go by this fast, I can't imagine how the 30's, 40's etc will go by..........I guess I can just be hopeful and thank the good Lord that there are great Plastic Surgeons out there haha!
