It's clear to me that Bella had a wonderful owner in you. As a fellow pet parent, I know the heartbreak of telling them goodbye. Nothing I write here can make that any better, or hurt any less.

So just be kind to yourself, soak yourself in your best memories of her, and give yourself permission to grieve. Her loss and your love for her are both worth all the tears. You have my most heart-felt condolences. :(
