I’m so sorry that is HORRIBLE :(
I don’t think your partner feels that way, if they’re willing to help and caregive and you feel safe with them just know that what the doctor said is NOT the reality. They are horrible nasty evil people, and just because they view it in a negative light, doesn’t reflect that you are cared for and WORTH caring for and your life is worth something.
I’d say maybe ask your caregiver/ partner for some reassurance so that your brain doesn’t focus to hard on what the doctor said and can be reassured by their own word
