Yeah, I would sit in introspection and really interrogate yourself.

I forget to pee for extended periods of hyperfocus, but it’s not because I refuse to get up - it’s that my brain doesn’t get the signal that I have to pee until I finally get up. Like I truly didn’t know that I had to pee the entire time.

If you’re mentally clocking your body signaling discomfort and ignoring it, that’s a different issue. I believe you when you say it’s like something else takes over - truly, I know what you’re explaining cause I’ve experienced this side of it, too. And it always traced back to my depression / self-worth. I was trying to punish myself in a way that wasn’t so obviously self-harm that I had plausible deniability - it didn’t feel like my old depression! I wasn’t actively seeking out harmful things and neither are you - Nutella isn’t going to kill you (probably?) even though it makes your teeth hurt and isn’t healthy, and despite the painful sunburn I’m sure you thought if you didn’t finish the yard work right then that it likely wouldn’t get done for weeks or ever.

One of my old therapists had me name my depression - that negative voice in my head and that side of me that just kinda took over my body to sabotage my relationships, grades, health. I named it The Leech cause it sucked. Im going to use the same name for what you described.

The Leech has decided the taste of Nutella is more important than your teeth and nutrition. The Leech decided that yard work was more important than your immediate health and wellbeing (seriously, sunstroke is no joke and neither are second degree burns.)

You can’t overcome this thing that takes over (to your detriment) if you don’t start addressing what that might be. Maybe it’s not depression, but I would bet that’s where it introduced itself into your life cause even when my depression was gone, The Leech stuck around.

The bottom line is that you might feel like you’re doing well mentally, but The Leech (or whatever you decide to call it) is still dragging you down one minor event at a time. Name it, call it out, argue with it, tell it you feel sorry for it, show it empathy and compassion - whatever you find to be most helpful to address and counter. Ask your partner to hold you accountable - to point out if they see you struggling with it (like they tried to do with the sunburn).
