Hi Alyons,
If things go according to plan I will have gone through St Jean about 10 days before you intend to start. I just want to reassure you that although you may be on your own - you will not be alone. As one who started alone on my first Camino in 2005 I can assure you that you will meet and make friends very quickly, even more so because you will be on your own. Read more on this forum and you will see similiar comments to mine frequently. Go with an open mind and enjoy.
Buen Camino, Janet
