I have a friend who is treating depression for feeling lonely all the time. We used to call him every week to have a coffee, a beer, a pizza or whatever and he never did because he had no time and he was always busy or tired (as we also were). He kept doom scrolling until the day was over
That's kind of how depression works right? The things that could fix it (socializing, exercise, etc) are also the things that are hardest to do.
I'm not sure that I read your tone right, but being disappointed in a depressed friend for not hanging out is like being disappointed in a friend with a broken leg for not joining a soccer match.
