yes this most definately is mercury or other metals. Do you sometimes experience extreme panic or anything else that sends your nervous system into hyperdrive, or do you get really paranoid about things? if so I'd say you are copper poisoned too and must take zinc. I found magnesium taurate helped with the obsessiveness that mercury caused, dunno whether it was the magnesium or taurine that helped, prolly both. If you think you are copper poisoned it is critical that you get this sorted out too..
