Cleaning up to not fall into despair or whatever

My dog died two days ago. I still can't process the grief, I've cried in 1-5 minute bursts, when I think to myself "my dog is dead" I don't FEEL anything. I know it's coming but it just won't right now. When it does, I don't want to feel suffocated by my apartment. I have a foster dog that I met through donating his leftover food. She's another motivation to get my shit together.
