(throwaway because i have friends on my main account) 

hi! just for reference so the rest of this post makes sense: i’m currently 17 years old and in high school. anyways, since i was 12 years old i knew i struggled with my mental health, though i could never really place exactly what it was. recently, though, i looked more into what BPD is and how it can manifest itself, and everything started to make sense. especially after learning about what quiet BPD was. i know i can’t diagnose this myself, and i’m seeking a professional opinion to either confirm or deny my suspicions. because i could be totally wrong and this could be something else entirely. however, it’s not so easy for me. like i said, i’m 17. i still live with my parents. in the past when i tried speaking to them about my mental health they shut me down. they told me i was lying for attention etc etc. i can’t bring this concern to them. if i do, i’m certain history will repeat itself. 

so what i’m asking for is: how can i go about speaking to psychologist or someone else who is qualified to diagnose BPD without telling my parents? my school offers a psychiatrist, but i’m sort of apprehensive about speaking to them because the last time i sought mental health support from my school they told my parents even when i requested them not to (because according to them, i’ve “been suffering for too long”) and it led to a fight with my mother. should i give the school psychologist a shot? or is there another way i could about this? or should i just wait until i move out since i’m going to be 18 next year?

thank you so much!
