I've missed 2 deadlines for uni am I cooked?

Barely any explanation other than my mind in lectures is so jumbled that I write down the wrong deadlines. I'm taking in information then I'm concentrating on trying not to look like a weirdo cos I want friends then I have such bad brain fog lately that I somehow put the deadline on wrong date every time in my calendar. What excuse do I even give this time? I don't even know if they can kick me out or not because I swear I get given no information other than a deadline but I still mess that up.😭
