I thought I was in love, yes I was head over hills for someone, and when it ended I felt the pain physically in the pit of my stomach. It was one of the worst feelings, to have loved someone so much that it hurts when they didn't love me back. I am so grateful for that first "love" and "heartbreak" because it pointed me in the direction of the most wonderful man and I couldn't be happier. If I would have stopped living because of that one heartbreak I wouldn't be where I am today, in love even more then I was before.
You just need to remember that there is always another door opening to a greater adventure and the hurt your feeling now will pass and you will love again!
