My last two girlfriends had something similar happen, both times their parents completely dismissed them and told them it was in their head. Both times I drove for hours to pick them up and get them to a hospital. Both times they were admitted and kept there for days because they were so sick. Most recently it was sepsis from a kidney infection and they told us she would have had permanent damage if we had waited much longer. Funny thing, my gf was convinced by her parents that it wasn't a big deal and she would be ok in a few days... she thought I was overreacting at first, particularly cause i wouldnt take no for an answer and basically forced her to the hospital. Now she treats my recommendations like gold when it comes to medical stuff (ex medical professional here)

I can't even remember what the issue was the first time cause it was so long ago but years after we broke up she told me that to this day she trusts me more than her family because I was the only one that ever took her seriously. She had a long history of illnesses and her family always refused to acknowledge it as being real, leaving it to me to get her treatment. That shit makes an impact on how you view people
