Inn my ocd upsets people

I am so worried about getting the wrong things at the grocery store that I ask them if they are sure they want such and such a thing at the grocery store 50 - 60 times. People hang up all the time when I talk on the phone. But I have to get things rights.My husband gets so angry that he usually ends up getting angry and going to the store himself.I don't why this is so upsetting if someone did this to me I wouldn't care.I also like to talk about gross nurse stories roaches and maggots at dinner parties when people are eating they get mad I don't know why I don't know why.
