Trish, as all the others have said, don't worry. I started out walking with a friend who suffered with very painful feet and had to leave, so from Leon I walked on my own. Before Leon we had always met, lost and found lots of people, but walking on my own I did get to know people even easier. I suppose when someone is obviously a unit - friends, couples, even Camino families - it makes it that little bit more difficult to ask to share their table, walk with them or start talking. When I walked alone I was never alone, and I started not only taking the initiative to contact more, but I also felt I had a constant companion: My Camino. I even started thinking and sometimes talking about it as a separate entity (which no one seemed to find strange, luckily).
Then I did find two Camino sisters and walked with them for two weeks, sharing rooms and walking as a group. But when they decided they had three days left to walk to Santiago, My Camino only had two days left and they understood that. So I said goodbye to them in Melide, walked on to Santiago on my own again, and waited for them on the square when they came in the day after me. I was with them, but I was also alone, and I had a responsibility to My Camino, to follow that and not them, if that makes sense. And I will do that again. Next time I will start out solo and walk (with) My Camino and see where it takes me.
Buen Camino, Trish - it will be a great adventure!
