I think the degree of attachment issues and core Shame plays a role her. Sitting with my feelings sometimesoon means sitting with " you are a worthless, broken, repulsive, unlovable piece of f@$! ING dog s $÷@. You do not deserve to be alive. You are not human. You are fundamentally and completely broken and destroyed"
You can only sit with stuff like that so long before it starts to gut you and tear you apart.
