I appreciate this question OP thanks for asking. I will tell you what it's like for me personally but first I wanna suggest a source/topic I feel may be helpful learning for you. I would look into the depressive cycle. As many of us regularly go in and out of depression and experience this cycle. There's great articles and youtube videos. As it can be different for different people I feel by looking into that and comparing your specific depressive behavior could help you understand better what not being depressed may look like for yourself.
