Is AUTHOR wrong in the post ? POST : Alright, so a little bit of backstory here.

I am horrified of loud noises. I think it began with a fear of fireworks which escalated into a fear of balloons (even unfortunately yelled at my uncle because he was rubbing a balloon in my ear), gunshots, even loud talking, and now recently, thunder and lightning. I am terrified of these noises or anything associated with them (i.e. I can't be in the same room as a birthday party that has balloons or (recently) a rainy day for fear of thunder and lightning).

A year ago, I had a traumatic moment when a lightning bolt struck our neighbour's tree and split it. I saw red, white, and blue flashes that actually hurt my eyeballs. The sound of the thunder clap after the strike made me drop everything I had, clutch my ears and scream like a banshee. I was horrified and in tears with my heart pounding in my chest. I was trembling, my brother called my phone to see if I was alright, stuff like that. I've been afraid of rainy days and dark clouds ever since.

Back to the present. So I'm at my dad's house and he has to go to work, which means that I can go to my grandma's house. Grandma's house is about 500 feet down the street, about a two minute walk. Being in the South, we have a lot of rain problems. I get anxious when I see dark clouds or when it starts to rain because I'm scared of thunder. My dad wants me to take my umbrella since I was carrying a lot of stuff. But after hearing a clap of thunder, I try to say no and that I was afraid of the storm.

He brushes it off and I try to explain that I'm scared of my umbrella catching a lightning bolt, as well as the sound of thunder. He again brushes it off and says that my umbrella is plastic (certainly doesn't feel like it). I argue with him for a bit about the supposed myth that holding an umbrella during a storm is sure to attract lightning (I believed it).  
So I'm sitting here looking at the storm and borderline about to scream because I'm having very bad flashbacks about that lightning strike. My dad lectures to me that I'll be fine and that umbrellas don't attract lightning, that I'll have the same chance of being struck with or without an umbrella, and that I should stop "acting like a baby."

I explain to him about the lightning strike I heard and (personally I believe) that I developed a kind of PTSD from it (or some kind of trauma). Dad tells me that "PTSD is only for military or army stuff" and I'm sitting here about to honestly bawl my eyes out because of the thunder. Either way, I take the umbrella and go outside, but then I start hearing loud beats from someone's car and interpret it as thunder booms. I start to RUN down the street, terrified of the sound.

Am I the asshole for arguing with him and refusing to leave the house?
