I don't think depression ever fully leaves you, not when its to a severe or lengthened level. It leaves a scar, even if you're "better". I think that type of depressive episode is life changing. Just like getting in a car accident, or having some other type of trauma.

That being said, I think you can still lead a full life being recovered from depression. And I think it is possible to cope with clinical depression and manage the symptoms in such a way that you can live a decent life at least, if not better. Coping may require constant meds and therapy, of course.

I'm not sure if I see my depression as seperate or as a part of myself. While I was more depressed, I was really negative about it and having trouble seeing a difference between me and it. Now, I see it as a seperate part of me and as more of a condition. Kind of a mix?

Nice to meet you and thanks for asking this question - It's thoughtful and something I've asked myself many times
Take care
