I read a private blog today that simultaneously made me feel better and broke my heart. Chronic illness, either physical or mental, is great at that. To know you're not alone in the struggle can give you the strength to face it and keep going, but it's also sad to know someone else, especially someone you love, is living in the same realm of suffering as you.
Life is weird and unpredictable and sometimes very hard, and we can only live it one day at a time. We could all stand to remember that it's all any of us can do, and therefore we must make a conscious effort to act (and react) accordingly.
