Executive Function

Hi so I’m an AuHD woman and I have been medicated for my ADHD since 2022, I am really struggling with executive function I feel so burnt out all the time despite not over working myself, I go to the gym at least 3 times a week and do socialise but I don’t work as the last time I did it triggered a huge mental crisis, I feel so tired all the time and struggle with basic tasks like tidying and organising things, everything feels like a chore, I don’t really understand why I feel so burnt out and disregulated and procrastinate doing anything that requires slight brain power or movement, does anyone have any advice on how to improve my executive function- I am really struggling with this, TIA
