Anxiety in Relationship 😪🚘

So I’ve noticed over the past 6 years that I’ve been with my husband that whenever I know he’s driving or on the road with someone, I have like major anxiety to the point of physically throwing up, especially if I haven’t heard from him in awhile. Like today, his phone was messing up all day and it wouldn’t have any service on an off, well of course it’d act up while he was on his way home and he was unable to get it back working for almost 45 mins (the drive home was around 20 mins) so naturally I was freaking the fuck out thinking the worst — that he had been in an accident. I have this urge to call twenty thousand times and ask our neighbors if they see his car at home just because I’m terrified of something happening to him and me not knowing. Anyone else suffer from this? Idk how to handle it. Today pushed me over the edge. Normal people don’t do this. They don’t react like this. I tried to calm myself by telling myself that I KNEW his phone wasn’t working and that I was sure he had made it home safely, but nothing worked. Im not sure if my fear is of the actual car ride itself or not knowing my husband is safe. I’ve also noticed it mildly with other family members but not nearly as bad as it is with him.
