You're a different person now, it's just sad because I miss you a lot. Strangers can become best friends just as easy as best friends can become strangers. Friends and family members evolve over time, we all do, so this is a sad but true fact of life.
I never believed people when they said how much it hurts to have your heart broken, until it was me, lying on the hotel room floor, gasping for air. Don't ever say that you haven't killed anyone, because you killed me that night.
Once you come to this point, it is when true healing can begin. You learn who your core people are, who will help carry you through. There is nothing wrong with admitting you can't do it all. That is true strength.
Missing someone is your heart's way of reminding you that you love them. Instead of being sad choose to think about the good memories and all the joy you shared. This does make me think of my wonderful Mom. I miss you soooooooo much.
