Is it normal that anytime i think it's about myself or someone dying?

In my life, I have to just react and try not to think that much because anytime I do it's about myself or someone who is close to me dying. I could be waiting on someone to pick me up and they're not answering their phone and are late to pick me up. I don't know why this happens but it does and no matter what I do it won't stop. Is this Normal?
