Joan,
I am also a female, I have traveled alone all my life, this is my second Camino, and yes: I'm nervous and scared to death.
I saw a Camino documentary on YouTube where a priests says that what we really carry with us in our Camino is our fears. In fact, I realized that the bigger your backpack, the more fearful you are. Of getting sick, of not feeling comfortable enough, of feeling cold, of getting wet, of getting blisters, of getting forgotten by those back home, of developing tendinitis, of twisting an ankle, of not finishing the Camino, of failure, of getting bored, of going hungry, of not being able to sleep at night, of becoming a different person...
This priest also says that the Camino is a metaphor for life. Because life is a journey. You repeat in the Camino a condensed version of how you live your life, so how you live your life becomes more clear to you.
I used to be a pretty fearless person, to the point of recklessness. Until I saw both my parent pass away a couple of years ago. Then I became afraid of everything - ultimately, of death, something I had never faced of thought about before.
Things started to change when I decided to do the Camino again a few months ago and booked my tickets. As the day approaches (45 days to go!), I get more anxious and jumpy. Particularly because I DID get very sick in my 1st Camino. I caught a virus in Majarín and had to stop in Ponferrada and return home.
But now every step I take in preparation for the Camino, in my 10 - 15km daily walk in the heat of one of Rio de Janeiro's hottest summers ever, the stronger I feel and the more confident I get that everything will be alright. Yes, I'm jittery, but I am also happier by the day, because conquering our fears is simply exhilarating.
Buen Camino!
