I think you're extremely lucky to have been out of the office all this time. Compare yourself to teaching staff who had to go back to schools in early January to support the children of key workers/vulnerables or people like frontline NHS staff, bus drivers, supermarket staff etc who had to work all the way through the pandemic even when numbers were sky high.
Cases are very low now and we need to go back to normal. Just stop overthinking it, get the vaccine and go back to work.
That is really not helpful. There is no need to make it a race for the bottom, and does nothing at all to reduce the OP's anxiety for herself.
@QuietBatPeople1 You've had some very good advice on here already. If you have anxiety, then no amount of "reasons" will convince you overnight. If it wasn't anxiety about Coivid or vaccines, it would be anxiety about something else, because that is the way you are currently "hard-wired". So you do need to speak to your medical practitioner about your anxiety; and I would also suggest that if it is possible you speak to your employer, especially if they have an occupational health department that might be able to support you.
I could tell you that the risk of developing a serious case of Covid is extremely low and was even very unlikely at the height of the previous waves. That is true. It is also true that the risk of the vaccines is very very small and even smaller than the Covid risk. That is also true. I could make you a list of much riskier things that you do every day normally that are far riskier than either of those things - but you'd probably worry about those instead!
This anxiety is an illness, and there is nothing at all wrong with having an illness. You do need help with it though. Things would be so much worse if you give up your job because of the fear of something that almost certainly won't happen. And that is the reality - all the bad things you are thinking about almost certainly won't happen. So I can't prove this, but you will be absolutely fine. It's taking that first step that is always hardest. Think about the positives - getting back to a chat with your friends at work, getting out of the house - whatever makes you look forward to it rather than being overwhelmed by the fear.
Good luck - you can do it, you just have to believe that you can.
