I have to admit, I find this thread / poll confusing.
I have life stressors (such as my mom passing away and not being able to find my brother)...I deal with them head on, in therapy and with the help of family and friends.
Some stressors, such as crowds, I will avoid only if I am feeling unable to cope. However, most of the time, I do what I need to anyways (toughing it out and gritting my teeth).
Triggers such as certain songs, incense, hair color etc., that bring the past flooding back are dealt with differently. I will stop what I am doing and take a walk to calm down, when calm I will ask myself what the trigger was, what I was feeling and thinking, and then I adjust accordingly. I will usually contact my "T' if it is really bad and I almost always journal the experience.
Invasive 'thoughts' are more like stressors to my mind, while invasive 'memories' are more like flashbacks.
I hope I am adding something to this conversation and not making it more confusing for everyone. Please correct me if I am wrong in my thinking.
