How do normal people feel ? do they feel safe all the time ?

im in a constant state of panic and fear, i cant focus i cant relax, im never present, but recently i discovered that if i tell myself all the time that im safe, im safe, im safe, i start to become present and feel safe, but is this how its normal ? my brain chemistry is prety fucked i guess, would making myself feel safe all the time have negative consequnces ?
