Excellent advice here. I was 28 when we moved from Connecticut to upstate SC, just north of the I-85 corridor. The storms tend to track along that highway.
We rented a singlewide for the first couple years, "bugged out" to a friend's house a few times with children, dog, and cats. Saw a yellow-green tinged sky. Had the breath knocked out of me by the force of the rain hitting me while taking my cat to the car. Never saw or heard a tornado (sound like a train) though they came close.
If you are in a mobile home and the weather people tell you to leave, seriously consider it.
Don't be complaisant, but don't worry yourself, either. Crank radio, fresh batteries, water, all good ideas. Have important papers in a convenient place so you can grab them, or just scanned and saved in an unsent email.
If you get caught outside and it's coming lie face down on the lowest ground nearby, don't go under an overpass, dangerous place.
If you can't get into your shelter grab a blanket and head for the bathroom, or a closet in the middle of your house, lowest floor. Wrap yourself in the blanket and get in the tub. The blanket is for flying debris.
Now I'm living in hurricane country, but tornadoes get spawned from those. All the local TV channels go to tornado coverage nonstop on broadcast until the threat passes. No basement here, I'd go to our main bathroom if a storm got close.
Be aware, not scared.
