Common in all incidents is that the client did not get support from the people who should have taken care for him. Identify what is the most traumatic in the situation, check SUDS, correct PR and apply EFT, the TFT trauma algorithm or EMDR for this incident. It might may be different from what would be traumatic for you as a therapist. E.g. in a situation of child sexual abuse, seeing the eyes of a mother looking at the abuse without stopping it might be much more traumatic than the actual physical abuse. Different sensory aspects of the physical abuse may vary in importance.
Some people react more to what they see or feel, others to what they hear, taste or smell.
Where it's possible to shut off experiences of genital stimulation, this might not be possible to other forms of abuse, especially oral. Usually, the SUDS of these situations are reduced by the work on the initial one. The connection between the craving symptom and smoking will be considerably weakened by the time more recent incidents are revisited. A lot of processing happens when the client remembers the different occasions where the craving response showed up. In re-remembering each occasion after the extinction of the negative emotions of the first one, cognitive integration takes place.
