Who am I?

I know I use to be a light hearted, positive, rational funny girl. Now I'm a SPAZ.

I'm on the verge of my 40th birthday...I have one year old twin girls. I'm a newly wed and I think Im losing my mind. All of this somehow equates to me growing into a wildly, unconventional dramatic SPAZ. Everyone loves a spaz but not when the spaz is....
-Sarcastic
-Peculiar
-Aggressive
-Zany

Is it my age or my job or my homelife that has created this monster? I really dont know but I suppose we are going to find out.
