Family member works at the same hospital

Long story short, I'll be starting residency at the same hospital that one of my family members works at. The relationship has significantly deteriorated (due to personal decisions that I've made that they disagree with, ex. choice of significant other) to the point where they'll comment about how I'm unfit for my profession, how patients won't want to get treated by me (amongst many many other criticisms/blaming/emotional manipulation, but the ones I've mentioned are the relevant ones to work). Is there anything I should do, or should I just not say anything and hope they keep it professional?
