I'm having a hard time understanding my feelings today. I'm happy and depressed at the same time. I feel like I can do anything, have tons of energy, am getting a lot done but I'm also depressed and having thoughts of suicide

I've never had more conflicting feelings at the same time before, does anyone else experience this? I was only recently diagnosed, is this what's called a mixed episode? It's so confusing, I've never felt both extremes at once before.
