Worried

I just moved into a new house and a completely different neighborhood and I didn’t want to let my cat outside because we live by a busy street. This morning, as I was leaving for work she ran outside and I didn’t have to time to go after her so I left really worried. Well its been a full 24 hours since that happened and shes still not back home. She’s been outside in the past and came back hours later. I’m scared if she got ran over or lost😩
