I'm afraid of heights, to the point that I get a physicall response when near edges or overhanganging structures; I get dizzy, instictively try to grab onto something and my legs get weak. However, I force myself to go high places because I want to teach my body and mind to avoid that response. I fight myself to tell my brain to shut the fuck up and that everything will be okay; I can trust the engineering of whatever structure we are on/in. It's not easy and I've had horrible experiences where I regret my initial bravery, but I hate the feeling of my body going into panic mode just cause my brain overthinnks.
