Told to get over it

3 weeks ago I had a full hysterectomy and ovaries removed due to haven’t endometriosis cancer. Am slowly starting to get back to going out on little walks . Today I got my daughter from school for 1st time since I had the surgery, had another woman ask me what’s wrong said oh am still in a bit of pain getting over my recovery. The answer back threw me oh you still on about that you need to get on with it I would have by now . . I couldn’t believe what I was hearing an I just had to walk away and the fact I never said anything has got me wound up so much . Don’t me wrong am not saying I want to argue I’ve not got it in me to do that at all school around kids or other people am just so annoyed, angry that this was her attitude. Am not sure now what to do I just can’t believe she said anything like this anyone got any advice please
