hope you don't mind if I jump in here---but the itchy, crawly feeling of the skin I believe is an indication of a toxic bowel---have you done any bowel cleansing---toxic bowel equals toxic mind---kinda like which came first---not to minimize your emotional trauma, just suggesting that it could be a contributing factor---when I had mercury poisoning I suffered with "mad matter syndrome" like symptoms---I was full of fear and anger---and was pushing everyone away from me---my cats (one sensitive one, which I almost lost as he got ill), friends, family---so I feel for you---hang in there---things will get better, especially if you keep cleansing and trust your higher self---
hugs,
