I told her it was my choice to come in to assist. I also said I was not getting at her for working from home - no idea how much or how little she was doing but that isn't my business.
Can you really not see why she was annoyed with you?
What is a ‘sick line’? You said on the previous page that you were ‘on a sick line for a week and three days’ but worked from your bed.
I’ll be frank: I think that I might have reacted similarly to your colleague. You sound like hard work. She comes into the office, having been working from home. You ask for admiration for your unstinting devotion to the business (which, let me tell you, will not give a flying you-know-what about you when the chips are down) and ever so passively aggressively simper that she shouldn’t feel bad about having worked from home rather than coming into the office and doing loads of extra work to help other people like heroic little you.
Your reaction is disproportionate. All this “I didn’t get a wink of sleep” stuff. She was brusque with you, but you invited it. Get over it. Now you’re determined to “get her” (a direct quote from one of your earlier posts) for something. If you can’t make bullying stick, you’re going to try to “get her” for something else. It’s chilling.
I hope that I’m wrong, but you sound like the passive aggressive old timer whom everybody wishes would leave but nobody dares challenge because you’d immediately kick up a massive fuss and most likely go off sick with stress, taking as many people down as you can. If you’re not, you are at the very least unhealthily attached to your job and a semi-professional martyr. The type I and many others dread working with.
