About me, my life and my question...

Wow, so where to start!
I guess I should start with a small introduction about myself.
My name is Melina and I’m 27 years old… I'll be turning 28 on July 25th. I’m married, have been for 4 years, and have 2 dogs. My husband’s name is Gonzalo and my dogs are Rocky and Lio. My background is Italian, more specifically, Sicilian. I was born in New York, but moved to Virginia when I was 4. I have a younger sister, Joanna, and a younger brother Chris. My parents are Julia and Tony, and my grandmother, who is like my second mother, is Giovanna.
So what else…I have a big family, as most Italians do. I recently started a new job back in December, it’s okay but my commute is horrific (I’m sure many can relate). I don’t have any hobbies, although I do enjoy reading…not enough to consider that really a hobby per say....but I do enjoy it from time to time.
So that’s really my life in a nutshell.
As to why I’m starting a blog….I honestly don’t know. I guess I have a lot to say and no one to say it to, aside from my husband but I think he’s a little sick of hearing me complain all the time. What’s mainly been on my mind is, and I’m sure it’s a very common question, but basically, what is the purpose of my existence? I’m in a place in my life right now where I feel so lost and in limbo, like I’m neither here nor there, just kind of floating. Not happy, not miserable…just there. Completely different than what I expected coming out of college. It seems like we leave there with so many dreams, so many expectations. Everything seems so reachable…and as I’m getting older, I feel as if I was in a fantasy world. Everything I thought I’d be, I’m not. Depressing, right? Well…I’m just not ready to give up yet. However, now experiencing life a little bit more, I realize, what I thought I wanted coming out of college, I don’t necessarily want anymore. So my question…what do I want?
