First off, you're ramping up your stress/anxiety level when you lard up "Waking up with apocalyptic thoughts [snip]. I feel very powerless. I find it hard to get through" with "I need to get to my F* job tomorrow".
Today is today, tomorrow is tomorrow. So... what are you doing/have you tried to manage waking up with apocalyptic thoughts today? Also, rationally... there are likely to be many thoughts that you will have today that will compete for your time and attention. Waking thoughts are not necessarily the ones you HAVE TO give your time and attention to. I had to learn how to "restart" my day when my mind was beset upon on waking to an assault of awful/negative/uncomfortable/fearsome thoughts. It is a good tool and can be learned. Also... factually, they say that people have many thousands of thoughts every day, some 10's of thousands and even like 30,000. I choose the ones I want to attend to... it is not the other way around.
What tools, strategies, coping skills do you have in your tool box to manage the thoughts you are having right now? Can you be open to the possibility that factually and rationally the thoughts you began with today are not necessarily likely to be the ones that you are stuck with and also that by the end of the day/evening there is the possibility that you can feel differently?
Waking thoughts are the best opportunity to practice management. 26-30 days becomes a new habit... 6 months a new behavior.
