Well the first step would be to see if we can get the Omni-tool adjusted for a medical scan, and from there SAM can probably get a pretty good readout on your physiology.
And I obviously don't understand everything you're going through but I had a somewhat similar sensation of 'am I me' when I figured out how much SAM was doing for me so if you need to talk or something I'm here. Or at least have a name of someone whose helping me through that.
