We make changes in life to grasp happiness.  Life builds barriers to make us contemplate on difficult decisions.  We walk each day wondering if we've discovered a new beginning, a new happiness, a new love.  
What happens when happiness turns into a state of panic.  You have no grasp of the situation, but you find that sitting back and trying your best to relax is just not good enough.  I've always been one to worry, but at the same time, I'm sure many people in my life have worried very dearly about me.  For instance, I've always sent my mom my itinerary for 99.5% of my flights.  Nevertheless, I always called her when I stepped into my hotel room sometimes 1-3 hours after landing.  I would imagine the sigh of relief when she heard my voice.  
I've always been one to call or text or email the one's I love to let them know that I'm OK.  I don't mind getting a spam of text messages or calls from them wondering where I'm at.  Who wouldn't want that!  What happens when I start worrying about someone.  My thoughts start to wonder.  Are you hurt?  Are you stranded?  How come I haven't received any notification?  These are the points in life where you don't take anything for granted and your heart starts to crush as the seconds and minutes go by without a word.  
This is my mortal flaw.  I care too much. (Thanks Mom <3)  And when the caring is taken for granted, it reduces. But magically appears the moment I receive a text or call.  What happens when that call or text never happens?
I get in the state of being unwanted.  The feeling where I don't matter anymore.  This really sucks.  Life revolves the way it does and it sure doesn't revolve around me.  You'll always find me asking you to call or text me when you get home.  But when I fall asleep worrying and wake up without any word, the worried feeling increases drastically.  I get restless.  I think it's time to relax and take things into my own hands.  I wish I felt this way for more people.  But its my heart that's running the show.  
I don't want to feel this way.  I don't like feeling this way.
