I found my phone after it was lost for 3 weeks and then lost it again 4 days later.
It's still gone!! I'm about to go rage-o-pathic about this thing!!
I think that a lot of us are "crazy," and we risk a lot of our current health issues getting worse through stress or lack of effective treatment. However, I don't that most of us will go on to spontaneously develop psychosis or to treat imagination as though it's reality.
It could be the anxiety worsening your focus/recall and that's why you can't find items you're looking for.
I've been plannning on getting a basket to set on my desk to put my phone, keys, and wallet in. Always losing them....
