Friends' comments like this do nothing but harm. She's has no idea under the sun what she's talking about and sure didn't help you one bit. I'd tell her kindly that after she has a knee replacement and revision then she can comment about your recovery. I think you're doing great! This is a long process and you are doing it well.One of my friends (whom has never had a surgery) told me I needed to get used to this because it just might be my ' new normal.' Holy smokes that upset me. I don't want this as anything other than a point at which I get better from. She didn't mean to be hurtful - just honest with me.
