You are the one best informed to decide how best to protect yourself. That said, these data are unambiguous: living in house with a gun increases your risk of death or injury.
I don’t believe the data on carrying in public are clear yet, but if notice you carrying a gun in public, my family and I will leave the area. I don’t know you. I don’t your state of mind. I don’t know your level of training. I don’t know what makes you feel unsafe. What I do know is that you’re potentially a deadly threat that I can avoid, and so I will.
