Just the act of smiling will make u feel better.
Look up at the sky, see the beauty of nature.
Count your blessings. Can you see, hear, smell, walk? Even if you can't do these things, there are still blessings to count.
Is there someone somewhere who loves you? God loves you too.
Smile. Let the corners of your mouth come up, let those eyes crinkle. Do u feel better?
