I have generalized anxiety over minecraft?

I'm pretty sure I have generalized anxiety. Because, like I get little adrenaline rushes over the smallest things. I love minecraft, but I'm scared of caves and the dark. Even, though I play on peaceful mode. I put up a lot of torches. I'm scared of the bats, I don't know why. I know they are little black flying things, I know minecraft isn't real. But, I get really scared.
