My boyfriend OD'd on over half an ounce of Meth back in November, prior to the OD he was using heavily, in the 3 days before the OD he was paranoid, had chest pains and had been snorting not smoking it. He survived the OD but has terrible psychosis despite being clean since then. He is convined I am conspiring against him and has cut off all contact with me. I have done nothing wrong but it doesn't matter how many times I tell him this or show him proof, he doesn't believe me. He thinks all random events have significance in an elaborate plot against him. He is on Risparidone but it doesn't seem to have any affect on his paranoia. Will this ever end? What can I do to help him?
