I am working in a high stress professional job. Retrained late in life so I am at a junior level. About a year ago a friend asked me to do her a favor and do some work for her relating to my field. Later she came back to me and said there was an error in something and didn’t say it outright but blamed me. At the time I was very sure of what I was doing so I do not see how I would have made that error. This was all done for free. And after this happened about two separate times she brought it up almost as a joke which really offended me.
Now she has asked me to have a quick look at something I thought she was going to do herself and just wanted someone to check, I asked her last week did she do it and she said no and basically wanted me to do the whole thing this weekend. Problem is that firstly I will refuse to stand over it in an official capacity and I think I should warn her of this because I will absolutely not take any responsibility for mistakes. When I am officially at work, everything I do ultimately goes through the people at the top so if there is anything off they will catch it.
Secondly have had a difficult couple of years from mental health perspective but I have learned to take care of myself and put up boundaries when I need to.
She will see this as my not being a good friend and not being helpful.
AIBU?
