Depressed captain

The title says it all, im lost again due to my heart. I look at all my friends and everyone's happy and I'm all alone. Sure they come up to me your not alone where with ya. It's just not the same, I just feel like why am I here, can't I be happy. It's like a dark cloud that will never go away. I wish someone would just save me. I save people all the time. Why can't it be my turn :(
