I think her parents divorce really did a number on her and she'd benefit from speaking about this at therapy rather than her vague "anxiety" issues. I'm in NO WAY blaming her parents for her issues I just don't think Zoe coped well. In the last few vlogs she's mentioned things her parents used to do over the holidays (like the tree from their garden thing) and I think she must likely get a bit sad over the holidays knowing that family unit and house are no longer around. I think there's a big part of her that clings to 90's nostalgia because of her family and childhood being somewhat idyllic at the time. It's still BS she claims to love family and visiting them and never goes to see them but it does also explain why she might have an aversion to it, as it brings up negative feelings.
