    Chemist (and biochemist) here. Organometallic compounds of Mercury are primarily dangerous because Mercury ions bond fairly strongly to soft ligands like sulfhydryl groups found near the active sites of enzymes. This can result in the displacement of the metal ions or otherwise disrupt the structure needed for enzyme functionality. Mercury metal OTOH is considerably less reactive. It is not safe to breathe in for prolonged periods of time but it is no where near as toxic as its organometallic derivatives are. Dimethyl Mercury for example, is extremely dangerous. A single drop has 100+ times the organomercury content needed to kill someone.

    My nicknane was “walking encyclopedia” when I was a kid so that tracks.

    In my undergrad I went from being a chemistry/physics double major to a biochemist and finally finished my chemistry degree. (I am not far from having 3 degrees) I studied ASL, German and Japanese, modded video games and competed in a semiprofessional starcraft league. I wrote instrument guides and procedures for undergrads, contributed to papers on bioremediation, synthesized nanoparticles using genetically engineered enzymes. I developed a method for a plant alkaloid assay and a new way to reduce noise in an experiment designed to measure the rate of certain reactions that occur in extremely diluted systems. i.e single or double digit number of molecules in the entire sample.

    Now I tutor college students in chemistry, physics, math and biology and work on computational chemistry projects.

    I was officially diagnosed with ADHD three years ago.

    There is no one test to get diagnosed and you can’t self diagnose. Even your therapist can’t if they don’t have the training and experience to do so.

    ADHD diagnosis involves interviews with people that knew you when you were a child, any mental health professionals youve worked with and a series of tests measuring intelligence, executive function, self questionaires and how you interact with the tests and the people testing you. i.e that indecisiveness would be taken into account in a professional screening. You aren’t really being tested for ADHD or autism so much as trying to rule out alternative explanations.

    And its also why you shouln’t diagnose yourself with either of them despite what a lot of people think. Because sure it could be ADHD or autism but it could be a lot of other things that dont respond well to the same things that autism and ADHD do and you need people that actually know how to rule those things out or if it happens that you arent in the ADHD/autism tribes, figure out what tribe you actually belong to.
