Wad happened?

Today I was watching a show showing someone broke a girl's leg just to forbident her from playing basketball. At that moment I felt the pain and the sadness as if the girl was myself... The scene keep apearing in my mind... Watz wrong with me? As if there was a stone stuck in my heart... Felt weird and pain at the same time... Remembering some time before, I was watching high school musical 2. I somehow feel really damn jeolous looking at the two main character... Wad happened to me... I had never felt so damn crazy before... Why do I feel jeolous so easily? Why do I feel so heart broken easily? Why do I get effected so damn easily?
