Music Dilemma

I was just singing "The Phantom of the Opera" for kicks and I remembered that I need to fill out this form for Karen (my current voice teacher) so I can continue studying with her. This made me remember that I have a dilemma. I don't have a problem with Karen, I just feel that I need to be pushed a little more than she is doing. I would love to go to Scott over at Pacific because I liked him ever since he was my judge at Solo/Ensemble my 7th grade year. Some reasons for not going are 1) he's way over at Pacific and I don't really have time to drive way over there, 2) Karen is right here, and 3) I kind of like being lazy. With Karen, I've had the confidence to say, "I would like to sing this song sometime" and she'll usually let me do so. If I moved to Scott, I'd feel overwhelmed and definitely not as confident, so I most likely wouldn't be able to sing some of the songs I would like to sing. Also, with the no time to go over to Pacific, if I had Sil 5th period I know she would let me leave once a week to go sing. Unfortunately, drama is 4th period and I don't think that my 5th period teacher would be as understanding (though I don't know who that is yet). And I know I could always do the "I have a doctor's appointment" thing, but my parents wouldn't be too fond of that, since they don't like lying like that. Also, my family has a problem with being too loyal. I'd feel bad about leaving and my parents would too. However, my parents are fine with whatever decision I make. They would be happy with whatever. I'm kind of at a loss as to what to do. Please let me know what you think.
