Saying goodbye to my beloved dog

I said goodbye to my dog, who I had been with for 10 years, last November.

I think I feel even more attached to it because it is my first puppy.

I still miss you, and it feels like you are right beside me, so every day is hard to bear...

I used to go for walks every day, but now that I have nothing to do after work, I feel so incredibly empty.

I've been deliberately exercising and trying various things, but maybe because time hasn't passed yet, I always think of you and miss you before I go to sleep.

I loved you so much when you were here that I told you I loved you every day... Now that you're gone, my heart is breaking.

How should I overcome this?
