Am i normal? yes of course you are. There is nothing wrong with you at all. Anxiety isn’t something that makes you odd or mad or even wired. You may feel like this sometimes but i can assure you that you are as normal as everyone else in your life.
Even if people that don’t know think it’s a little odd that you have anxiety, then do what i do an assume them to be wired for not having anxiety, Trust me it works.
Our body are just more over active to fear and there is nothing wrong with that, in fact in makes us much safer than others, we are more alert to our surroundings and have a better idea of where and when is safe.
Don’t be ashamed of who you are.
