I don't know if this counts but I think maybe I'm losing my mind a little, or like, my words? And it’s really embarrassing because the kids are asking for help with their maths and English homework and I just stare at the page, and the word for like… the opposite of up… it’s gone, and then I feel SO stupid, and I don't want them to think I'm dumb, and then my mum calls, hundreds of miles away, and she sounds tired, and I feel guilty for even thinking about myself, but has anyone else felt like this, like your brain is just… emptying out?
