Does this happen to anyone else?

The sound of someone's voice just makes you angry? This happens to me with a few individuals. After a while it gets so bad that hearing their keys as they walk into the office triggers that irritating feeling. I was put on a medication once that stopped it for a while but I don't remember what it was. I was able to apologize to one person for treating them so coldly and we are fine now. But it's happening more often now. My mother is very loud and I feel that it has affected our relationship. Well that's a whole other issue.

Has anyone found any helpful remedies for this?
