I do believe it eases over time. My therapist saw her therapist for 10 years. She didn't rush the process, and after that, she was very comfortable as her own therapist as she calls it. Working through attachment issues is deep work. I think being patient with ourselves, compassionate, and understanding will ease this and if you're going several days, that sounds like progress to me.

I've also begun using DBT to help me take the edge off the intensity of my emotions and it does help.
