Mine is a mix of both. Since I got medication and therapy I have fairly long respites and the depression only rears its head every so often. But I know that there are certain situations that can cause it to return, like too much stress or family problems, so I try to avoid them, or curb them with things that help, like time spent with friends or light exercise. I think at the end of the day it's different for everyone but I agree with Elana, it really works best to attack it from both sides.
