lindberg,

Your question is very vague. Can you explain it further, please?

PTSD is becoming the catch word for any unexplained anxiety or other symptoms. It is grossly over-used.

Stress also has many aspects. Some are external. Environmental or other toxins, sensory stressors, etc. can be avoided in many situations. Others are internal, meaning they come from withing the person. Many internal stressors can be reduced or resolved with proper understanding and choices in thoughts (CBT Cognitive Behavioral Therapy)
