It takes time and this forum really helps. I started getting "confirmed" seizures about 2.5 years ago, it took a tonic clonic for them to see my "fainting" and "blackouts" weren't mental and opened the door to look into epilepsy, and even after the TC it took a year and a half and a drop seizure for them to finally run an EEG that confirmed the epilepsy. I was diagnosed in April and it was hard. I had the worst anxiety of my life from it, I woke up all hours of the night shaking uncontrollably from the fear. I went to therapy it was so bad. My therapist wanted to commit me and would have had I not been a single mother at the time. I developed severe agorophobia from it, afraid of every thing about life. To top it off I knew it could have been worse and felt like a baby for letting it control me so much which set the depression in.
What really helped me was getting closer to my faith. I realized everything I was afraid of, that the rooted fear was that this diagnosis would kill me. I was afraid to drive, afraid to shower, afraid to walk on concrete, afraid of sleeping, afraid of being awake, afraid of having the seizure, afraid of not coming out of a seizure, afraid to cook, to be in public, to be alone... You get the point.
My real fear was that it would kill me and the SUDEP didn't help that fear. It is a real risk but its not a common risk if you can manage your epilepsy. It took until two months ago before I would finally take the meds, the fear of being on them for life was very real as well. But going on them I'm more optimistic. My faith though has cured me of my debilitating anxiety.
I understand faith is not for everyone but it was/is my miracle drug to combat the anxiety. Other tricks I used along the way before my faith became strong... I know it sounds silly but any time you feel afraid, any time you lay awake in fight of flight mode from the anxiety unable to sleep, tell yourself over and over "I will be ok. I will not die. I am having anxiety and that is all. My life is not over, I am healthy and alive and I will be ok." These positive affirmations can do wonders for your mind set.
Hang in there, with time the diagnosis gets easier to take.
