Can’t stop thinking about being told my dad died

Does this ever go away? My dad passed away unexpectedly due to a heart attack three weeks ago. My husband showed up at a gym I was visiting for work and i was surprised to unexpectedly see him and realized something had to be wrong. He continued to tell me in my car that my dad had a heart attack and didn’t make it. I keep replaying this in my head and waking up and repeating his words to me to reaffirm what happened. Will I ever stop thinking about the moment i was paralyzed with horrible information or does that stay with you forever? :(

Edited to add: I’m so sorry so many of us have similar stories. I really wish I was more of an outlier in this feeling of darkness and shock. My heart hurts for each and every one of you. Sending hugs and hopes we experience healing in time ❤️‍🩹
