So my family have asked me to get help

I am no expert but it sounds like a response that falls on the (admittedly wide) spectrum of normal. Perhaps a chat with someone your family deems to be an expert would reassure them? Your breast care nurse could be a good first port of call. I agree with @afraser, your family's new normal is very different from yours. But also, what you feel now may not be what you feel in a year or so from now. We are not static creatures. Let us know how you get on. All the best.
