Circumstances triggered my flashbacks, but mine were different. I got them all up and out at once over a period of 5 years and never dealt with them again after each incident came up. This happened with me after I recovered from panic and anxiety attacks.
My daughter had severe flashbacks like you have Scott and she is fine now. She still has some flashbacks, but she copes well now and they don't interfere with her life.
There is a lot of hope so just keep taking it one day at a time.
