Staying out of your room to keep you safe sounds good. I hope you have a good visit and can stay distracted. Is asking for PRN if you need it an option?
I'm including some information below about injections if you would find it helpful to read. I have put it under a hide so if it is unhelpful you do not have to see it or read it. You can ask me questions about injections if you want, but if it is better for you to not think about it or understand any of it that is reasonable too.
