Im always double checking myself, and all it takes is thinking I might of seen something that isnt there and im in a panic!
Like today at work you get an email bleep...when an email arrives - and I thought I heard it twice and checked...but no emails...now im worried im going bonkers and im hearing things? Is thinking you are hearing things like that mad, or ok?!?
Does anyone else get this? Im also always double checking if I see something? Its like im looking for something to be amiss!
