The emergency services people you were speaking with deal with people in extreme distress as a normal part of their working life. Stress impacts different people in different ways. Some lash out, some collapse in floods of tears, some turn to drugs and some go catatonic. I'm sure the emergency services workers were pleased to be speaking with someone stepping up and taking responsibility for a serious problem who only stumbled over a few words despite an extremely stressful situation. You should feel proud of yourself.
