Every time I needed to do something like carry something, I made myself leave it behind and go without it. I forced myself not to get attached to anything for security. Reasoning being that I would be really buggared if I didn't have it with me one day.
Shortly after my accident 16 years ago that started all this, I had to wear my 'armour' of long sleeves clothes etc but I worked at getting that to change. Scarey but I did it.
Now I often wonder if I did it the right way. Perhaps I should have put my faith in something I could carry so then I at least may not feel as insecure as I do most days.
I don't think it is wierd, I think now that it is whatever makes it work.
Whatever helps you through your day.
I would suggest that you try and minimise the attachment as much as you can though so you don't get too dependant just in case you can't find it one day.
