Rest In Peace Allen😔

So two days ago I lost my bunny😔🥺

his name was Allen. I found him on the streets and I wanted to bring him home. I did I have him everything he needed. At the time I was very very depressed but he made me so much happy to the point that I wasn’t sad anymore. Everyday I had a real smile on my face because of Allen. He was my best friend, he was my happiness, he was my cute little bunny. But now he’s not here anymore. I miss him terribly I want to run around with him, play with him, feed him, I want to give him his favorite treats. It hurts bad I just want him back💔 Can anyone give me some advice on how to handle this situation without me coping the wrong way?
