Hi Sharon,
I feel for you.....but it does get better!
I don't have any miracle cures for you, but try to relax and ignore it to the best of your ability. I had exactly the same problem! I tried it one night and just about panicked so I ripped it off and forgot about it for the next several weeks. But, my headaches were becoming more severe so I knew I would either have to get used to a bipap or my time would be up real soon. Since I was not ready to die yet.....still have too much living to do! I knew I would somehow have to get past my panic and use it. It was one of the harder things I have done! Some people don't have any problems - I did.
I had a good long talk with myself and then thought - if others can do this then so can I!
I put the mask on and laid quietly on my left side and concentrated on other things. I have a very strong mind, so I forced myself to RELAX. After awhile the bipap synchronizes with your breathing pattern and gets more comfortable. Everytime I put it on it takes a few minutes before it perceives my breathing pattern and stops fighting me. It also took several nights to get the settings so they were comfortable, your RT will work with you on this.
I was also a mouth breather because of sinus problems since 13. So I got a face mask - tried several before I found one I liked. It only took 2 nights to get used to it once I stopped trying to fight it. Now I cannot understand why I fought it so hard at first. It is a LIFE SAVER! I can now get a good nights sleep and wake up rested, this has not happened in over 7 or 8 years.
Try using it a bit during the day just to get used to it. Lay down for an afternoon rest and put it on. Have a good talk with yourself......YOU CAN DO THIS - I DID.
Once you get used to it life gets better as you will have more energy. My breathing was also better during the day, likely because my diaphragm got some rest while I was using the bipap.
I can totally relate to what you are saying, but please relax and convince yourself you can do this - because you can!
You can also ask your doctor for a mild sedative you can use at night.
Hope this will help you a bit......ask me anything and I will try to answer.
