You asked if you should be worried without a male onboard. Where you live now is there a male around? Do you feel you need a male around to feel safe and confident? Are you strong and independent? Will you be on the road or living in one area?
It has been my experience that women are, most often, far more capable than they may give themselves credit for. I believe that attitude counts for everything. If you think you can, then everyone else better get out of the way. Women,by nature,can endure situations that would have men wetting their pants. The fact that you are considering this life with a 2 1/2 year old tells me two things. 1. You are weighing your options and this one appeals to you. 2. You may have no other choice. Regardless, if you can,go slow. Research your options. Be very, very careful of offers to help you personally. As anywhere else in life, there are people willing to take advantage.
To answer your question,I think with some planning and situational awareness you will be fine. Learn everything you can about the life you are planning. Remember, people are basically good and will go out of their way to help. The idea that the world is collapsing around us and that civiization is evil is simply nonsense. With the right attitude, people find that the world is populated by wonderful people, eager to meet you, embrace you, help you, comfort you, care for and love you.
I wish you and your lucky daughter the very best life has to offer and I envy your journey.
Take care, Michael
