Hopefully you won't have a long journey with CRPS, but even if you do, you'll learn coping mechanisms, you'll find meds and procedures that help, you'll learn how to decrease your pain by adapting, etc.
I wouldn't wish this disorder on my worst enemy, but it is possible to find contentment and even happiness in your life.
And if you do go into remission, you learn not to take your health for ranted ever again. You'll know what family and friends you can count on, You'll realize that you're much stronger than you ever imagined, etc.
