I'm the same and it's really out of character for me to get annoyed by things like the sound of people clearing their throat or eating but it's started to annoy the hell out of me.
I was on a bus yesterday and getting really stressed at a kid sitting at the back yelling down to his mum at the front the whole time too and then her other child kept screaming with one of the worlds most annoying screams. It's times like that I think "why am I doing this"

but then I've never really liked other peoples kids. Just those of friends and family.
