Can sleep deprivation and depression affect your Hero function?

Has this happened to you?

I’ve lately (for the past 1-2 weeks) had a terrible sleep schedule and feel like my brain has been mush (though the past two days I’ve felt better as I’m been correcting it). I’ve caught myself not really paying attention to reality, but also not thinking. With that it’s just felt like I haven’t really used Ne (my dom function) lately. But this has also happened kind of often before (getting into a bad sleep schedule). After fixing my schedule for a few weeks, I mess it up again.

I also feel like I haven’t really had much motivation to do things like write (which is my main interest) and don’t get things done during the day when I tell myself I will and set up a schedule for myself (since I’m currently unemployed and have a lot of time rn), maybe it’s because of the sleep deprivation that I don’t have motivation? And not necessarily being depressed. I also have ADHD & feel like that plays a role in my inability to follow through on schedules I set up for myself sometimes.

Yesterday I found myself questioning if I’m really an ENFP because like I said, I haven’t really used my Ne much lately (maybe I have & just don’t understand Ne that well). That and feeling the desire to stop rotting in bed (because I don’t really go out.) and experience life and wanting to be more present and feeling tired of pondering useless things. Like is my cognitive function shifting? (Since I’m kinda young still 23 1/2)

If anyone can also help with this identity crises too, I’d appreciate it lol.
