What really struck me was the conundrum even ordinary people faced daily with letting go and/or holding on to intimate relationships. As someone with Borderline Personality Disorder (BPD) this is a struggle close to my own heart. A core feature of BPD is the presence of serious interpersonal problems. People with BPD tend to have intense, unstable relationships, characterised by frequent wavering between strong clinginess/dependency and sudden withdrawal.
Do note that this post is directed towards friends of those with mental illness; not caregivers. Sometimes we have to take a step back when a relationship is too harmful. This is an unavailable option for a lot of caregivers but, when it comes to other relationships, walking away is sometimes the best option.
