I think it can do. For me it just highlights how little my family care about each other. I have siblings, and we all live far apart but never is there any contact on there when I post something. I see friends posting pictures of their families or their achievements and their siblings making comments etc but that will never happen with my siblings. Like others have said though, customising is key. I learned how to unfollow the posts that make me most uncomfortable and now I hardly see anything on my wall apart from the people that actually matter.
