Hey. I can relate. I often feel like I am broken as I struggle with normal adulting tasks and behavior, like cleaning and chores and crap.
It's weird. I have a complicated job and managed to get several degrees but for the life of me I haven't figured out how to keep up with laundry or opening mail or not letting my place turn into a disaster zone...

I think for me it's a combination of not being able to keep up stuff that I am supposed to do today and then somehow do it all over again tomorrow, As well that when depressed I don't give a **** about any of that stuff. It's overwhelming.

I wish I had good ideas how to help with this, but i haven't figured it out yet.
I do know that beating myself up for it never helps, even tho it is my go to thinking at times But I do hear you and can relate. Hang in there.
