Hi Dragonmamma,
Marianna mentioned this site - she couldn't be more right. I had a ugly recovery, but the understanding and support people showed on this site was the encouragement that kept me hopeful.
Dealing with our emotions is not an easy thing, particularly fear. My dentist used to tell me he had patients who were frightened to go to the dentist until they were in agony. Facing brain surgery is obviously a lot different than the dentist. First and foremost, realize that these operations are going on all the time, so you have to not dwell on any particular outcome, but realize that you're in good hands with the medical team you have chosen. Second thing, it is a bit of a gut check, we're asked to be strong, and it's your turn in this stage of your life to be strong. You will amaze yourself how strong you can really be. Third, have a really good support system with your family and friends, they will help you through this. Finally, if you're a person of faith, seek out God in prayer to help give you the tools to handle this. I hope my post was of some help. I will pray for you, to have the courage for this, and for a speedy recovery.
God Bless.
