Do your episodes have a trigger, or not necessarily?

I can feel I'm falling back into a dépressive épisode. My mood shifted from one day to another, like it usually does.

The thing is, I could never see anything that could trigger it. My hypomania is always triggered by lack of sleep. But depression? Nothing. It feels like it just happens. My brain just shifts for no fucking reason.

If there were a trigger at least I could work on it, but I swear to God my life was good, and I've been stable for months. Nothing particular happened the last few days that would explain a depressive episode. I just don't understand why it's happening to me.

Just let me be happy bro wtf I'm so tired of this shit
