What Were You Like Before Depression?

What does it mean to "figure yourself out"? I've spent the last few years trying to understand my mental health and time and time again, I end up in the past. I know who did what to me, and how it affects me today, but I'm now faced with a bigger question: what do I do with all these answers? A big focus of mine is to figure out who I am when I'm not depressed, and who I was before my trauma.
