“Writer Fern Schumer Chapman, who was estanged from her brother for over 40 years, wrote in her book Brothers, Sisters, Strangers that when siblings cut ties, they’re left in ‘a world of secrecy and shame’, even if they’ve made the right decision for themselves. The feelings that come with this decision are complex and will vary by person depending on why they’ve chosen to cut ties.”
