hi,i am also bumping up your post, as i hope someone with experience can help you.
welcome here :)
i don't have experience with fentanyl but i wanted to welcome you here and bump your post so someone will come and help you... i don't want your post to get overlooked !!!!!!!!!!!
as for the anxiety, i know it is hard when you are going through the situation you are experiencing right now but try to work on those catastrophic thoughts that are coming to your mind when you think of your fears and what you have ahead....face each one with some constructive thoughts, don't run away from them, face them with positive thinking... ... People have got off the patches so you will be able to do it too and it might take some time but you will find other ways and help with your medical problem.... try to breath very very slowly ( 5 seconds inspiration, 10 seconds expiration).... the breathing exercises really help to calm down ourselves, concentrate only on breathing.... even eating an apple very slowly and focusing only on eating it could help to alleviate those moments.....
ok, i really hope that someone can help you with the patches but be patience cause weekends are sometimes slow... All the best :)
