Sometimes we need to befriend fears so they don't drag us down, but sometimes fears are also warnings. A certain amount of fear or anxiety is not bad, it just warns of danger and sometimes you should be a bit fearful, we have demonised fear when it's only just an emotion, being OVERWHELMED by it is what is bad. Pd. if you have sleep paralysis like I do, you see "ghostly things" in the darkness LOL XD it's just a sleep disorder but you will never overcome that fear because it's an automatic response of the body, primeval fears like darkness, intruders are coded in our lizard brain and when our body needs to wake up (due to sleep disorders) it triggers a fear to make you react (flight or fight response). I don't know if exposure to a fear until we desensitize to it is the solution, no expert but I think it's more sensible to understand and embrace your fear and be aware of what they tell you, and in time time harness and control it.
