My dog just passed

Hi everyone, meer hours ago my dog passed away. My little Ivy was only 7 years old, she was alright 2 days ago then began being sick and having diarrhoea. I took her to the vets at 3pm and they gave us medication and thought she had severe diarrhoea. We go another 10 hours and I decide to take her to the emergency vet as she doesnt seem right, sadly she passed in the car on the way there. I owe my life to Ivy, I genuinely would not be here today without her being in my life.

I currently feel completely lost, im waiting for this nightmare to end but I know im already awake.

Ive never lost a dog before, Id like to remove most of her belongings asap, beds, bowls, food etc. Ill keep her dog tag and anything more personal but the rest ill donate to a local shelter, I feel like removing as much as I can will help for some reason?

Ive told the people closest to me already and ill make a lovely post on social media about her in the coming days.

I seem to go through moments of pure tears and then it stops for a bit before starting again.

I live alone, I still have my cat. Any advice on how to handle this? I feel like a fish out of water with no way back right now.
