I second the "be careful" post just above mine. I've never been drug tested, but they do generally have you sign a narcotic agreement that allows them to do this whenever they want. They want to see that you're taking your meds and not hoarding nor selling, and also that you arent taking any they didnt prescribe.

Im not one to recommend suicide, but I can absolutely understand where you're coming from. You feel like your world is crumbling and there is nothing to live for. I get that. Completely.

Please see a good pain management doc. Explore all avenues. Maybe you need an antidepressant. Lyrica can actually case depression so that might be adding to the problem. Dont be ashamed to let your PM doc know about your thoughts. Assuming you arent currently suicidal they wont involuntarily commit you to a psych facility. However, if you need that treatment... GO! I know we cant get rid of CRPS, but imagine how much life would be if you could come to a point of acceptance and find a reason to live.
