I hope I'm not misunderstood! As far as I have understood it, routines do not take the disorder away, but can be a help in stopping a set-back. My understanding of the topic "routines" or "structure" is like this. Example: If one has been able to build a morning-routine even if that was difficult. That routine becomes a habit and one does not have to think about it. It becomes automatic. On the other hand if there one day pups up an extraordinary trigger, one will feel bad the next morning and perhaps want to stay in bed. It is in that moment one has to cling to one's routine to prevent a setback. To stick to the morning-routine keeps one going even if one feels like crap.

The same goes for other routines like eating regular meals, physical exercise, doing relaxation exercises, go to the grocery, do the dishes and so on.

I have understood the "routine" question this way: If one are able to follow one's daily routines in a time when life becomes difficult one can hopefully prevent a full setback of the disorder and after some days, perhaps weeks in some cases, be back on track.

That's why I posted the link I found. May be we can call such routines for coping mechanisms?
