I noticed in myself that my stuttering gets significantly worse when I’m having a depressive episode. There’s not much I can do in those moments to alleviate it, unfortunately. But as the episode passes the stuttering lessens and eventually (mostly, in my case) goes away. I would focus more on trying to understand and help your depression than the stuttering. It can be hard if healthcare isn’t accessible and everyone is different but there may be some things online that can help with managing or overcoming a depressive episode.
