Weeeell. . . First of all, I really want to reinterate to
you that your interest in anime has nothing to do with
whether or not you'll make a good officer. That was a very
spiteful and immature thing for your father to say to you.

On to the rest. From the sound of it (keeping in mind that
I wasn't there), it sounds like you did lose your cool.
Running to your room and pulling everything down off your
walls is an emotion-driven and uncontrolled action done by
a child, not something you would see from a mature person
who is thinking out each action they make and making only
actions that will further or better their position. This is
not something you should be ashamed of, it only means it's
an aspect of your personality that you have to work on. If
you are NOT yet an adult, you should not have to be always
as mature as an adult - or in your case, *more* mature than
some the adults in your life. Unfortunately, maturity at
your fingertips is what you need right now.

That said, part of the way you can get your parents to
accept your choice of cel collecting as a valid activity is
to present yourself as a *mature* young adult who makes
your decisions wisely. This means practicing complete, 100%
control over both your actions and your words. And it WILL
take lots of practice. You have to train yourself to be
able to simply stand there calmly and quietly no matter
what your parents are saying. There are few people who can
do this perfectly.

I advise dodging the issue while you fine tune your self-
control and learn some more about how to turn discussions
in your favor. I would find another address to which your
cels can be sent and I would end the conversation about it
with your parents. Another thing you can do is to make sure
you do not spend all your money on cels. (Honestly, if you
want to eventaully live on your own, you have to start
planning that now. Right now you have few financial
obligations and it is a perfect time to save up the money
you will need to eventually live on your own.) This way it
will be much more obvious that this is a HOBBY for you,
albeit an expensive hobby, but a hobby none the less.

As for addictions. . . There is a lot of kidding on this
Forum about being addicted to cel collecting. In reality,
it *is* possible for a person to be addicted to material
items of some sort (or even to spending money). Only close
self-inquiry and self-inspection can reveal if you truly
have an addiction. I get the feeling that you are *not* a
true addict - only someone who is facing a roadblock in the
path to differentiating yourself as an individual. Don't
forget that part of your parent's upset is coming from the
fact that you're not treading the same paths of interest
that they are. For most of your life, you've (willingly or
unwillingly) done pretty much what they want you to and it
is going to take *them* time, as well, to come to terms
with the fact that you are starting to become your own
person, apart from them and their household.

But this does not excuse the way they are treating you in
regards to your interest of choice. Do not react to their
words by sinking to their level, react by rising above the
situation and realizing that in the long run, it won't
matter at all what your parents say or think about your
interests. You need to respect yourself and the person you
are becoming.

But as another person said, this is becoming quite personal
and a public Forum isn't *really* the place. . . I invite
you to write me privately about it if you're interested in
hearing more of what I might have to say. ^_^  I'd love to
help if I can. . .

Many Sharp Smiles,
