Do I have liver disease?

Right now I am freaking out! I noticed the corners of the whites of my eyes are a off white cream color, Im scared its jaundiced. I asked my mom she said its just blood vessels but idk im scared, my skin color is a tannish olive color but its been like that for as long as I remember. Idk if my eyes are like because of lack of sleep, this whole year I only got about 5-6 hours of sleep on weekdays cause of school is this the cause? I have no other major symptom really? im just really scared my parents wont take me to the doctor idk what to do! idk if its jaundice or what please help im 17
