If absence of symptoms is unrealistic, perhaps people need to be looking at how they are managing their symptoms as an indication of recovery. If you are managing to go about your daily activities, then this is a sign that you are recovering. If not, then that is something you should be working towards with your doctors. I think your quality of life is the most important indicator of recovery, much more so than absence or presence of symptoms. If you are enjoying life, and managing your symptoms well, that is very much a sign of recovery. If you aren't, then you need to keep working towards this. How can you change your activities so that your quality of life improves.
At Beautiful Identities, I talk often about the importance of not being defined by your illness, but it is also important not to be defined by your recovery. Don't let the things you need to do to manage your symptoms define you. Your altered diet, accommodations at work or school, or your medications should not define you any more than your illness should. For example, if exercise is important in maintaining your wellbeing, you don't want to be feeling like this is the only reason to exercise, you should be finding a type of exercise that you enjoy, so that this can be a part of your identity separate from illness or recovery.
How do you define recovery? How do you avoid being defined by your tools for recovery?
