Max,
I do not know anything about saliva test so will not comment on that. You are taking good supplements for anxiety. I think you should do liver flush. Please check the Liver-Flush forum and ask questions. I would stay away from Hydrocortisone, a steroid will just complicate things. If you can get the Amalgam from your teeth out, replace it with white filling, that will help.
I hope that you are also on plant based diet and not eating processed foods.
