gosh, i can totally understand not knowing and freaking out. i would go to another doctor, definitely, because the one you're going to is obviously not helping you because they are not explaining what is going on with you. as for your rn stepdad, if i'm remembering right, i would not go to him. just go on your own. i know this is hard to do, but to find an explanation, it would be worth it. i'm so sorry that you're not getting any support with this. you deserve it. you don't need to be so freaked out like this; you need answers and you have that right.
