While I am not a professional, I would say that "yes" we can develop an anxiety disorder where we can be signaled to stress and even panic in certain circumstances.

If children grow up around parents that "argue and yell at each other" they don't know what that means but it "scares" them and compromises their sense of "safety". Children are constantly "imprinting" from their parents the entire time they are growing up and they "do" take on "stressors" that the parents exhibit to them.

As these children become adults, they do have these built in "alarm" systems in their brains that go off when they are "reminded of these stressors". If something happens that is "traumatic" on top of that? The risk of then developing PTSD is rather high. The truth is many people spend their adulthood learning how to "get over and recover from" their childhoods. See, your adult mind recognizes that people in a heated confrontation that has nothing to do with you doesn't mean you are "unsafe", however the imprinted mind you have in your childhood signals to you, "you need to be afraid".

Many of the "anxiety" disorders stem from "childhood stressors" that get imprinted into us without our really realizing it. Unfortunately so many parents felt that their children were not really affected by their home environments or when "mommy and daddy" fight in front of them and also making angry faces. Children "do" pick up on everything and they slowly develop internal stressors that tell them to "worry and stress in certain situations". Also if "mommy" is always too busy to actually pay attention to and "nurture" the child, the message of "unworthiness" begins to settle deep in the psyche of that child too.

PTSD doesn't just come from a "traumatic" event, it can come from being in a prolonged relationship of abuse and feeling threatened or from growing up in a toxic environment where you didn't really learn how to establish a true inner calm and sense of safety.

Healing from PTSD and an anxiety disorder does take time and therapy where you can slowly "identify" these deep stressors and then slowly learn to "self comfort, self sooth and develop skills that can slowly take over for the messages that remind you to "feel unsafe and stressed".

The "therapy" that is being developed now is to train therapists to recognize these symptoms and to take on a role where their priority is to help the patient develop a "sense" of "safety" in their therapy room. If a therapist is not providing this "safety zone" then they are not doing the most significant part of their job. It is very important that a patient feel "safe" so they can slowly reveal these deep "stressors" without feeling shame or judgment or that they are somehow "failing". So in essence the therapist is actually playing a role of a "parent" that can slowly provide that accepting and comforting presence to the patient that was not there for them when they were a child. At the same time the therapist has to be aware that a "transference" can take place because the patient is finally getting exposed to something they needed on a very "deep level" for many years even.

So if you are "struggling" and at a point where it has gotten to a point where you struggle to function day to day to stay calm and focused. You are dealing with an anxiety disorder and need to reach out for therapy to help you slowly learn why and gain skills to learn how to "self sooth" and slowly learn how to overcome these deep stressors that are really "not your fault" or mean you are "unworthy" somehow either.
