Depression is not caused by a single factor. Three factors must be present for a woman to live with this mental illness. Depression is a combination of psychological factors, genetics and personal biology.
With that in mind, a past traumatic experience can be a psychological factor that “triggers” a depressive episode. Oftentimes, if a woman suffers an overwhelmingly stressful psychological event, depression can be “triggered” later in life, especially when she hasn’t sought help in dealing with the event.
I spent quite a while trying to explain this technically, but it doesn’t come out right. Therefore, welcome to your author’s world and let her explain to you her own triggered depression*.
In January of my 1998 I had my first depressive episode. I’d rather not discuss the trigger here, but let’s just say it was enough to scar me for life. In February of 2007 my divorce was finalized (on Valentine’s Day, ironically!) and I was devastated that it actually happened.
January and February have been notoriously depressive months for me. Even if things are going great, underneath the smile, the promise of in-state tuition, the possibility of starting fresh in a new town, a big dark cloud still lingers over it all. I’ve become accustomed to this, but people new to my life aren’t. They don’t understand that it’s not something I can change and it’s just something I’m learning to deal with.
Depression can be triggered by sights, sounds, situations, and even times of year. This is different than Seasonal Affective Disorder, as it can happen in the sunniest times of year. It’s not a vitamin D related depression. It’s a personal seasonal depression. It’s triggered depression.
*”triggered depression” is not a technical term. It is a term I’m using here to explain the situation.
