Welcome to Healing Well. I'm glad you found us, but am sorry you're having such trouble with your first wafer change.
Try not to get too frustrated. This is normal and happened to me the first time, too. Just take a couple of deep breaths and try again.
I recommend standing up when you apply the wafer and arch your back a little so your stomach is flat. Use just a little bit of paste around the hole that you cut in the wafer. Apply the wafer from the bottom and work your way up. Use your fingers to smooth out any wrinkles. Then, clip the bag on and hold your hands over the wafer for a minute or so. The heat from your hands will help seal it to your skin.
Hope this helps. Good luck!
