This might sound crazy.
I do yoga - breathing etc. Had therapy for my stepfather committing suicide when I was 21 (I am now 50).
I often hear certain music and theme tunes from my childhood and my blood runs cold.
I know there is a false memory syndrome but it would explain why I have such trouble controlling certain emotions.
I hold down a job/ have two lovely DC, wonderful DH...
Or am I imagining this...
