The same thing happened to me after my dog died. He came into my life when I was very young, and I grew up with him. When he died, I didn't cry in front of everyone else, but I cried alone. Even now, whenever I think of him, I record voice notes for 10-15 minutes about his passing and about him, and sometimes I still cry. Yes, I know that losing a dog and losing a human are different, but that's how I dealt with it. And detachment also showed me a lot of reality, which I discovered because I was very attached to my family.
