Like others have said, I don't need a trigger, it just happens. However, that being said, this last depression that I was in and am still struggling w/ did have a trigger, and you guys will probably laugh, at least I think it's kind of funny and I talked it over w/ my T yesterday.

I'm in a very stressful environment at the moment. Both at work and at home. Well, I was away from home for 2 weeks, and all of a sudden I didn't have the stress at home all the time. So, my brain stopped producing all the stress hormones that everyone produces when under stress. After about 4 days I started to sink into a very deep dark place. The only thing that I can think of is that my brain and body were so used to those stress hormones that it didn't know how to handle it when they weren't there, and that's what triggered the depression. It's the only thing that makes sense to me.
