Oh dear! I wouldn't call that dream sweet exactly..! Glad you are feeling a bit better though
I understand there is more of a basis for such thoughts in your case than mine (I am less involved in politics than I am in exploring Mars...) But try as much as you can to distinguish between actual and abstract fears.
About forgetting important things...Would it help to make a list of very important things? Like things that if you forget about them it will be difficult to make up for it. Then stick that list somewhere you see it on a daily basis, be it a wall or a book, journal...And try not to worry about the rest. If you forget something...you've forgotten it. Don't beat yourself up for it. There will be a way around it
Watch something safe before you go to bed tonight. Or read a children's book. A good night's sleep with better dreams would definitely help
