Girl, I hear ya! I hit it too this year. (in about a month) I'm pretty depressed about it. Life is just not where I had planned for it to be at this point. There were so many things I had planned for myself to have " accomplished" by 30, and none of them happened. And I thought 25 hit me hard!!!
BTW, whenever someone reminds me that I'm turning 30, I remind them that I am NOT - its' the first anniversary of my 29th birthday. And I plan to continue to have those anniversaries for several years to come.
