TL;DR I have had major depression for a long time due to childhood, and recently coming out of it I feel empty, like I don't know myself. Has anyone ever been in this position, and can offer any advice?

I have PTSD/Anxiety disorder from childhood abuse, and I just recently have got to a point after taking meds and working on myself for a year, that I feel okay. But, in a weird way I feel like I don't know who I am now, or what that even means. I was depressed for years upon years, and it was almost like that pre-occupied me, and now that I'm better I feel, empty, It's almost like the depression and dealing with it and the things that caused it was my life, and now I'm in the process wondering who I am. I still like my old hobbies, and I generally can get some enjoyment out of older things. But what defined me before, I guess, was just surviving, and now that surviving is second nature I feel lost. I'd appreciate any advice, maybe it's just growing pains now that I'm able to live and grow.
