noise irritates me, and i have problem listening to someone when other noise is around. i get irritated at noisy restaurants, and the other day i couldnt even hear what was on the tv, because my child was making a noise.
Either you are a sensitive person or you are suffering from stress for the moment and need to rest. Avoid noisy restaurants and do not try to look at television when you have a child in the room. Ask someone else to look after the child if there is a special tv program that you want to see.
It might be a good idea to see a psychotherapist to investigate what might cause the problems you describe.
