I just LOVE when people argue, ignore me or shut down when I try to explain why things work or why something is happening for them, For context, my IRL was talking about how she'll get dizzy when she went to stand, I having mentioned that she needs more iron and salts in her diet to prevent that, she unfortunately argued and said she didn't and that she didn't understand why her doctor sent her to a nutritionist (she has suspected ARFID, as I was told before), and I yet again explained that her doctor took into account the symptoms she told me, and wants her to go to a nutritionist so they can figure out what she needs in her diet; My IRL got pissed and said that she didn't like that and she doesn't need help because it's "weird and unnecessary", I was starting to give up, so I said that her doctors were looking out for her and that it's normal not to like something but it still needs to happen (example: boosters), and all you can do is power through it. She then ignored me. wtf.
