There are times when you can pinpoint the cause of depression, sometimes not so much. It could be one little trigger… a candy wrapper crumbled on the floor, a leaf floating past a window you just happened to be looking out of, who knows?
Even if you could pinpoint what un-pressed you to begin with, what does that change? Do you immediately feel euphoric? Probably not. Sometimes you just have to ride it out.
So you avoid candy wrappers and looking out windows on windy days…then what? If you don’t know what will trigger the next wave, how can you avoid anything? You can’t… just ride it out. It’ll all work out.
