I'd go with you and do whatever it might be that helps you through it, if I was able.

Aw, thank you. I do benefit a lot from someone going with me and that's one thing I'm dreading about this: if my job as a carer does actually entitle me to an earlier vaccine (which technically it should but it might not for Reasons), I might be getting it sooner than the few people I'd want to bring along with to get them to chat to me to distract me / maybe let me squeeze their hand to get some of the anxiety out.
