How can I put up with so much then flip over the peppermill

In May my house was flooded from the loft down into three bedrooms which were ruined my furniture had to go into storage and clothes which I have needed since are not here I have no lights no sockets and no radiators which have been disconected I have had to. Sleep on a blow up bed since May and worst of all no friends able to come to stay .The various workmen who have come and gone have ruined my carpets but I have coped with it all as I just wanted it put right, so why tonight after cooking my meal which I was really looking forward to did I totally lose the plot when the peppermill poured out peppercorns all over my dinner and kitchen floor I think it was the last straw. Have you ever flipped over something trivial which makes you feel daft
