My brain has stopped working. I had a bereavement 2 months ago of which the mental load has been intense (think having to mediate family members to stop massive fights blowing up in the aftermath, all the nasty bitterness that rears its head in peoples grief), I have 2DC (3 and 6 who i am also helping to navigate with their grief), it's just been the Easter holidays and i have been looking after the kids solo, i have no brain power left and I have to give a presentation at work first thing tomorrow. I have nothing left, my brain has stopped working and I actually cannot string together a coherent thought together. How can I pass as a competent human and get through this? I don't feel prepared at all, I am mentally exhausted.
