i'm afraid i will not finish the big task in time i'm afraid i will finish the big task, in big stress, just barely in time i feel guilty of not doing anything about this yet.
an answer might be: be compassionate with yourself. you are not perfect and don't strive to be perfect. learn from your behaviour and adapt. do the things, free yourself from your guilt and your fears, now you can stop asking more questions.
but more questions are coming up: my head won't go quiet!
an answer might be: everything that was to say has been said but not everything that was to do has been done now is no time for thinking, now is time for doing. you can calmly and nicely let the voices quiet down and focus, gently, clearly, on your work
it is a practise.
