Well, buckle up. That is a real problem, compared to this.
The 3 times I had a home invasion, I needed a gun in my hand, but too late.
Twice it was a ruse that got me to open the door, and once I found the sliding door in the process of being opened, by a very large hand and me quite nekid, checking locks.
All three were very dicey situations and in one people got hurt. I used my wits,and prevailed, but I would have needed to open fire immediately in all three situations. They were all armed.
You are not scared yet.
