Welcome rose.crez, it is great to have you here. From an earlier post of mine:
I would suggest that your very first step on this forum would be to explore the various topics which cover your specific concerns. There is a large storehouse of information available at your fingertips, and the search engine on this forum will help find the answers to the topics you need to research.
It is a bit overwhelming when you decide to do something like a Camino. But if you take a big breath and focus on one subject area at a time it will reduce the overwhelming and anxious feelings you have. You can start by looking at information to help you decide which route and what time of year you want to go. Decide if you have the time and desire to do an entire Camino, or is your time limited and you want to do a bit of the Camino over a few years. Once you have firmed up those areas, then things will start to come together in you mind as you plan your trip. Just start reading through the various forums to get the feel of how everything works and how folks interact.
Once you know the above, the specifics of travel, equipment to bring, accommodations, budget, training, etc, will begin to take shape. There are many good guidebooks and resources, some can be purchased from Ivar's store -- this forum's sponsor. Other online resources are available as well, as I'm sure you've discovered already.
But I highly suggest that you spend the time on this forum researching the answers to your questions in the huge archive of posts, and once your mind has begun to put things together, folks will be happy to help fill in the missing pieces.
