Do parents mean to be demeaning?

As a senior in highschool I still deal with parents a lot.  I'm usually ignored by most of my family because I'm so independent.  It just seems that most of my interactions with my parents have ended in unhappiness.  I'm not a PERFECT kid but I stay out of trouble and I do what they tell me to.  It just seems like they are freakin out cause I'll be moving out soon.  I just wish they would relax.
