My grief vs my bf’s feelings

Kari

Background i work in healthcare and currently a patient I am very close with is dying and I’m still fairly new to the field and coping with death isn’t any easier today then it was when I started. So my patient is declining fast and it’s really hitting me like an emotional brick wall and i just feel like shutting down. Earlier before bed my bf asked me why do I “keep letting him down” he asked me to do something earlier and I had full intentions of doing it but when I went to go do it I couldn’t being myself to get out of the bed and do it. He came home from the gym and saw it wasn’t done and was upset I didn’t do it and seeing him upset made me jump up and want to do it because I felt bad that he was doing it when he asked me to but he pushed me away and insisted he do it him self. It’s not like im trying to use the decline of a patient to be lazy im just so emotionally drained I can’t bring myself to do anything. What should i do or say to him to not make it seem like im trying to use that as an excuse to be lazy
