What herbs help you feel happier and more energetic? Ever tried maca?

I have problems sadness, I'm not sure if I have depression....but I struggle to be happy sometimes. I also have a low libido. So right now I'm on combined ginseng for the last couple days (one capsule a day with korean, siberian, and american ginseng).....for the last couple days i've felt a little better with more sex drive. And next week my order for maca and horny goat weed are coming in. I heard maca can really get your groove on lol. I was wondering what other people's experiences are.
