You can try accepting that uncertainty is completely normal and healthy and can be your minds way of letting you know you need more information or more time to process the information you already have. No matter what, be honest about it with everyone involved. We all have to make decisions sometimes without enough information and sometimes even with none. Guessing can feel overwhelming but it always helps me to be honest when guessing is ultimately what I have to do. Making a decision when you are uncertain can be very uncomfortable but doing it and seeing that you survived can often help ease the discomfort next time. Good luck!
