Coping mechanisms

I'm having a hard time coping. I am just looking at pictures and videos all day since Saturday when my best friend left me in my arms. It's Wednesday and I know it's still fresh but I have to go back to my life. Sucks we can't get paid time off work for a death off a loved one for a few days. I've been going to work not concentrating. I come home to my son not playing. I feel like I'm obsessing and unsure how to stop the rumination and looking over every damn Ring video of him. He's just peeing outside in these videos but I have so much regret for not just hugging him more. I need to feel closer to him I guess.

Life took a hold of me with husband and my kid and having my senior parents stay for a while that I lost track of my Tofu. I took good care of him. But it was just that. I cared for him. I should've showed more affection. How did you all do it and go back to your lives? I'm wasting hours doing this.
