While you do decent job of outlining some of the common causes of trauma and give some historical context for how the traumatic of loss of a child has changed in recent history, you definition of trauma is a rather poor one.

You state "Psychological trauma is nothing more than how we measure our life experiences to those around us." Traumas are emotional and psychological wounds that are the result of a single event, or a series of (inter-)related events. Your generalization totally ignores the deep impact on a human's neuro-biology that a trauma will cause. There are a whole spectrum of traumatic experiences and the mental/emotional severity that accompanies each will differ according to each individual's coping skills, level of resilience and also often the quality of their support system to get the right kind of help when needed. Healing the damage of traumas often require a good deal of emotional / cognitive reconditioning work. Your definition characterizes trauma as though all that's required for it to go away is for the individual to stop comparing themselves to others and that's it, the problem is solve. That's a completely superficial and inaccurate understanding of the forces, and is not solutions oriented.
Also your final points that there's no answer or solution to the increasing isolation people experience from using social media and "medication and therapy don't help" are absolute over-generalizations. Yes there are limitatations but not cause to dismiss them absolutely. Also you comment "Nobody can understand us because we are way too much into our own selves, " is a cop-out. Yes communication and understanding at the highest level can be very difficult, but if you don't see plenty of examples out there you're not looking hard enough.
To paraphrase a guy who really gets it, 'there's no problem that in the world that human ingenuity, applied properly, can not solve. '
Cheers.
