Like I get that you can only measure health in terms of the holistic being and "healthy" is a very subjective word which reflects organism, environment, and community standards. Completely understand that you need a regimen of self-care practices, cognitive reframing of stressors (spraying the bathroom with blood as I writhe on the ground), and a diet without any gluten or processed foods. I'm antivax because I have an immune system and anti-doctor because they're Obamacare death panelists eliminating half the population. But say you did alllllllll that and you were vomiting a litre or two of blood which overflows the toilet and scares your dog. What component of wellness am I neglecting and how can I better align my energy (negative, anxious) with the universe? Should I go to a chiropractor?
Any blood in vomit more concentrated than 4C is cause for concern.
More testing is needed. Please fully dry samples of your vomit and send them to a lab for analysis.
