Have you ever been in a zombie state of mind in which you cant think or do anything that requires you to actually use your brain?? For instance, you wake up extremely tired,you’re tired/sleepy through out the whole day and can only do mind-numbing work. On these days its near impossible to think about the future,crunch numbers,read write/do home work. You could function, but can’t really think. I’m having that kind of day. Can anyone relate?
