Ha, you're right that we replaced some stresses with other as we moved from tribal societies to global civilization. In the past we had more of the external dangers from the environment, but increasingly people were able to defend themselves by predicting weather, improving weapons against predators etc. I think in the past we were more in touch with our natural needs and instincts, and the slow pace of "cultural progress" allowed us to adapt to changes with skills that we learnt. Nowadays a lot of people feel one step behind everything (constantly rushing with overwhelming demands of our jobs and social expectations, frustrated about things beyond our control like traffic, terrorism threat, politicians whom we didn't choose, endless technological upgrades requiring us to conform or perish...). As there is no one we can blame and direct our aggression towards we get angry at ourselves for "not being enough", and we never get a real outlet for our emotions to dissipate. This is different from wild animals who know exactly whom to fear, and after they escape an attack they will release the fear from their bodies by shaking (see TRE by David Berceli). Regarding safety I have the same problem, not only from childhood but also young adulthood. I'm constantly working through them but it's not easy to feel relaxed when you never felt safe to do so. Some people don't respond to therapy, and there could be a mismatch between client and therapist and the type of therapy... I guess the best way is to start with current stressors and try to track their root cause to something in your past, and release their emotional charge through your favourite mind-body technique (like journaling, EFT, hypnosis, whatever). We'll probably learn valuable tools in this program later. Important is that you make it your own and enjoy using the technique. Gradually you will feel more resilient and confident about yourself and life events will no longer be so overwhelming.
