I feel the exact same way. But I'm 35! UGH it sucks! But the best advice I can give you is to take care of your skin & body. It will make 30's and beyond much happier cuz you will look & feel younger. I'm terrified of being old and not being able to move around. So I do everything I can to keep in shape so my body will age the best it can.

I am NOT where I thought I'd be in life at this age either. But like the other poster said you just have to set new goals for yourself. I always thought I'd have kids by now. I just realized to not put an age on stuff like that. If it's meant to be then it will be.

I will say this... I don't feel much different now than I did 10 years ago. So 30's ain't so bad. lol :-)))
