Yes, avlady, we are designed from the time we are born to depend on a presence that will answer to and sooth us when we are hurt or frightened. We are all born with a certain amount of hardwiring that we developed along the way that has allowed for our survival. Yet, human beings are very fragile and dependent for a very long time and we really depend on our parents and others to teach us things so we can slowly take on skills where we can become more and more independent.

What nurturing does for us is it provides "chemicals" to our brains that allow us to have a sense of "safety and value". The human brain grows and develops "the most" within the first three years.

When someone struggles with PTSD they "long for things" and "struggle to find ways to calm down" because something "traumatic" took place. How well a person recovers will depend on the kind of "support" they receive after a traumatic event. However, for some individuals, their personal history can also affect their ability to recover as well.

If someone struggling is able to access a good support system, rather then having other people who keep telling them to "just get over it, rise above it, stop dwelling, calm down, stop over reacting, gotta just accept it and the list can go on from there,
they will not get what they need to "actually heal". Instead the person challenged "must" have a calm presence that can consistently reassure them no matter what they experience in the challenge of PTSD. There is "no" drug that can replace what takes place in the brain, that encourages healing, better then this constant "calm and supportive presence".

It has been recognized that people who struggle from PTSD often benefit from being with others who also have the same challenges. Why? Think about it. It is the same reason AA has proven to help those who struggle with no longer being an "active alcoholic". If you have another person who can "identify" and "sympathize" and may be further along in recovery as well, the support can make a huge difference.
Sometimes, two people with PTSD "can" trigger each other, because of how PTSD produces anger so quickly. So, it isn't "perfect" as a lot depends of the individuals back grounds and even certain beliefs. But aside from these challenges, it is helpful to be able to interact with others who "do" relate and can experience the same kind of "emotional ups and downs and even crippling episodes" that PTSD can present.

Validation, and learning new skills with support is what "helps" the most with the PTSD challenge. Therefore, finding a good support system is very important for anyone who is struggling, that can be a challenge because of the desire to withdraw, but if someone can push past that and keep looking for the right therapist and ideally a good support group, that will do much to help "reduce" they crippling symptoms as the individual sets on a healing path.
