This thread has been more useful than I can explain, I now know I am not going daft and today I made the effort with no panic to drive on the motorway, I remembered the last time i had driven on the stretch of motorway which upsets me now was when I was following the Hearse that carried my beloved Dad to his grave , so it now seems obvious why i get upset, so time for me to get a grip or get medical help, my dad would be furious!!!! Good luck all and thank you
