Pain is your closest friend. He never shies away from telling you when something is wrong. He's always there in your darkest moments. Pain never lies to you and if you listen properly, pain teaches you the most important lessons about yourself. Don't feel ashamed if you cry, pain is trying to help you get your emotions out.
The worst thing you can do is bottle pain. He just screams louder if you do, as he won't let you kill yourself like that.
Pain will always be there for you until you are happy with life again. Then he leaves, until he is needed again. He may not be the friend you want, but make no mistake, he is your friend, and he only wants to help you. So don't feel ashamed of your friend. Be open about him, let him help you grow and learn. Because believe me, the best people in the universe... The kindest, smartest, fastest, and strongest, didn't get that way by never listening to pain.
