Listen to your body. If you are feeling sad, check in with someone else. If you notice your overall vibe heading towards the black hole, take all necessary evasive actions.
My non-depression (or normal) me is a bit more energetic and creative than most people. I get high, yes, but its natural energy (maybe some coffee) and it's what I consider the real me. The undepressed me. Still, you might think I was high if you met me.
