Dear Angelsaround,
For any issue,full body Reiki, all chakras & extra chakra work where you are drawn during the session. Without the ability to do an individual session would say :anything that aids in balance of the emotional & the cognitive brains. For traumatic stress or anxiety, center on brain & heart centers, thinking & emotion: crown ( central nervous system), third eye ( autonomic nervous system) & heart (circulatory).
If the client is open to massage would recommend that since we often store traumatic memories in our body & massage can stimulate release.
However, as has been mentioned, professional counseling is wise.
peace & joy,
holobon
