I think we as a culture need to learn to separate those two conditions. I have what you describe, when certain things go wrong I tend to numb up about it. But my wife has the other kind where her natural mental state is numbness and it requires a combination of medication and lifestyle and cognitive behavioral changes to fix. I can understand that because I have anxiety and adhd that work like her depression.

In general if you have depressive symptoms and your life is shit or you have something you think might help you should try fixing that shit, whether it’s eating better and exercising or getting out more or something like trying hormones (gender dysphoria often has a similar blanket dullness feeling to depression), but if all that doesn’t work or if you’re unable to achieve these things or you have other reasons to believe it’s the broken brain sort medication can help, but it has its own trade offs for you and your doctor to discuss and decide.
