Yeah, I'm 30

So I am Thirty,
I am little conflicted about that
I have always thought thirty was old, but here I am at thirty. Does that make me old?
I don't feel any older. But I am! I feel I should have done more with my life.
I should have made a difference before now. i don't know what I would have done or should have done but...I don't know I just feel old, but not older. Does that make sense.
Its not like I am getting married or having a child. It is not effecting life life style. But still...I feel like I have failed at something. I didn't live up to something.
I am probably just going crazy or something. Tomorrow will not be any different than today. Well hopefully the weather will be better.
