If only we could ALWAYS remember!!!!! And if only others could learn! I have chronic pain, & used to have migraines (won't call my current headaches migraines, that's giving in to them!). People would ask how I could work and smile when I reported to work during my often 4 day long migraines. I'd tell them I couldn't just crawl under a rock (though that's what I felt like doing!), & besides - it takes less muscles to smile than to frown! And just think - when we smile, it helps us improve our mood, even if it starts as a fake smile! Keep hoping, because that's what keeps us going.
