I recall stumbling on this artist a while back (no idea how) and I read the 200 ish strips that were there at the time.
Eye opening.
Not sure if the below would be considered NSFW... mainly for language.

These comics are definitely a perspective I had never considered before. I would not dare say it's the exact same for all individuals with depression, but it helped me to understand more about depression. These comics won't help you understand it. I think that's the point. If you don't have it, you can't understand it. But it also doesn't mean you can't support someone, which these strips highlight as well.
Just to note, I don't have depression. I found the comic strips good for identifying topics of discussion though.
