Is this it?

Every time I drive to work I am met with a big poster that says, "Life, is this all there is?"  I began to wonder...what if it is?  Don't get me wrong I believe in God, Heaven and an eternity with my Lord and Savior BUT what I am talking about is this life, life here on Earth. 
You see I have never really seen myself as a glass looker; half full or half empty?  Isn't it really the same?  I have tried my daily best with being a wife, step-mom, daughter, sister and aunt but often wonder, am I doing what others are needing/wanting me to do?  I have days where I am all but resentful of the things I have to do  for others and then the days where I don't have responsibilities I am almost melancholy with the idea that I am not needed or wanted.  What is that?  That is me!
Whether it is the turning of the key at school not knowing what is waiting for me or hearing the phone ring and not knowing who could possibly be calling or what they want.  In my mind I feel like I am someone that wants to give, give what I can but what about me?  Escaping this weekend I feel like a butterfly coming out of her cocoon, not because I have been caged in anyway but because I am morphing into someone that can go and do on their own.
How did I get here?  I was a woman all on my own and all the freedom I could ever want, now I am a woman that has a job, family and responsibilities...I want a balance of all these things, I don't want to regret, resent or run away.
You see, I guess all people must feel that way but I don't want to feel that way.  I want to feel level with my emotions, I want to feel balanced in my feelings, I want to feel empowered not exhausted.  So when all is said and done, I am hungry for the next day not dreading what might be.
Is that too much?  Is that just "normal" for here on Earth?

I want to be passionate again, I want to feel on fire for life, I want more.
