Does anyone else with depression feel like this?

I feel like I have an open wound on my chest that just festers and never heals. With a real wound, you expect some sort of change. Maybe it will get better, maybe it will even briefly get worse as it tries to heal... but this wound just stays the same all the time. Nothing happens. It hurts now, it will hurt later, and in a month, it will hurt the same. Like my body is incapable of controlling it or having any effect at all.

I once had a brief period where I felt healing there. It was getting just a little better. Only a little—but it felt amazing. And I thought it was going to continue. But no, it stopped. Now, years later, it feels the same as after just that tiny bit of healing. Like in that brief period, the wound closed a little tiny bit. But it's still here and still "dead".
