Non weight bearing half leg cast?

I fractured my 5th metatarsal straight across a month ago and did not get a cast til' 5 days ago. It's really been stressing me out and me being my active/clever self has been trying to find a way around crutches when i'm in the house, when i walk around the house to do my essential things. eat, go down stairs, up, bathroom. I walk on my heel. I was wondering if this would mess up the healing process of my pinky toe or if this is perfectly fine. help please.
