You might not feel like it because of what your going through or what you see around you. You might feel powerless because most of what is happening is out of your hand. You can do One thing though, you can Smile. You have that power, you dont need a reason and if you want one you have a million in your bank of memories. Yes it might be coving your pain and people might not understand how you feel inside. What did you think they would do if they did know how you felt? Share your pain with a counselor and a stranger and if you have a friend that you trust with your life, you can take a risk and tell them to incase they can help. Otherwise smile and be proud of your self for being able to pull a smile like that while you are in whatever you are in. And God Says Job 8:21: "He will yet fill your mouth with laughter and your lips with shouts of joy. Your enemies will be clothed in shame, and the tents of the wicked will be no more".
