Getting nervous

As I get closer to the departure date I'm beginning to have quite a bit of anxiety. I have a lot to do.

When I think about the minutiae I have difficulty imagining it. I've thought a lot about what to eat. Dried fruit, nuts, oranges, cheese, ham and bread are what I plan on eating. Or variations of that. But I struggle to imagine me sitting down for a ham and cheese sandwich on the side of some road somewhere.

The way I'm going to carry my bag means it will be tricky to mount, but I've been practising throwing my leg over from the side without coming from behind the seat. It looks a little like the ministry of silly walks. But I can't visualise a way to get off that doesn't involve falling off or dropping the bike on myself.

What am I going to do when I need to go into a shop? Leave the bags?
How much water will I need to take?
How often will I be able to resupply?
Are the sand dunes I'm planning on camping on actually sand or gravel?
What time will I need to look for a sleeping place?
Will the nights be cold or damp? Will I need my tent?
How will I charge my electrical stuff?
How many pairs of shoes will I need?
What will I do about my rubbish?
What will I do when I need the toilet?
How easy is it to hitch if my bike breaks?
How far will I be able to cycle in a day?
What are the emergency numbers?

I have a cooler but am not sure how available ice will be. Or whether I will even need ice. I asked my Nana years ago how they used to keep things cold in the 'old days' and she said they'd wet a hessian sack and wrap the food in that. It would cool through evaporation. I'm not sure how plausible this will be for me, but I might give it a go!

There are so many silly little questions that are becoming very relevant. They are all solvable, but it is causing some anxiety. So I've been focusing on only the next step. Move out of my house. That in itself is causing anxiety. It's not easy moving out on a bike when you have nowhere to move to.
