Is this a normal side effect of leaving a narcissist?

I left a narcissist physically but mentally I feel like I’ve become more supscious and less trusting of people that I know love me and mean me no harm. The same people that came to my rescue at times when my narcissist ex was abusive toward me are the same people I now have illogical suspicions of. Is that a normal side effect of finally leaving a narcissist?
