If sympathy labor pain exist..

Every month that my boyfriend goes into really bad opiate withdrawals, I start feeling the same way and it gets worse each month. Like he just got his fentanyl patches from his doctor today, so he should be going down on his withdrawals.
There's no reason that I should feel the way I do that mimics his symptoms. Like freezing to where it hurts but blankets are too much. The last week, that's been me. I want to tear off my skin. I can't stand feeling freezing with my body hurting and not being able to do/eat much. I love him very much so I was wondering if anyone else has experienced anything like?
