I'm terrified of bugs and I travel with sprays lotions potions the lot. I have to check the room before I go to sleep and if I come across a bug and fail to remove it I have to sleep in a separate room as I'm paranoid that I'll be taken advantage of as I sleep.
Obstacles don't have to stop you. If you run into a wall don't turn around and give up. Figure out how to climb it go through it or work around it.
