Fear can be a good thing, in some cases. Tells us when what we are doing is dangerous.
Having a lot of questions is terrifying. Especially when there really isn't anyone or anything telling us the answers to everything. When I have too many questions, I answer them myself. Generally, it is a stupid answer, but it works for me
And some questions can be pretty fun to explore, like... what does that new ice cream they're serving taste like?

Anyways, I hope your fear finds its way out of your head and into something else.
