what school?
anyway my frank opinion is that yes, u're probably a crossdresser
at least, but that is no a big deal. Fantasy plays and a brief
escape of reality is what most crossdressers crave.
Yes there is the chance that u will get addicted if u start. OF
course u have to search deeper with regards to your envy of
schoolgirls, because perhaps your...... true self doesn't just stop
at being a crossdresser alone. I have to point out though, that
even if u dressed up, u wouldn't get the sort of care n pampering
from your parents or anyone else which u so envy. Indeed it can
cause yr parents others to misunderstand u and be particularly
nasty towards you.
Ultimately though, u have to consider if you will be happy doing so
or not. I would encourage you to explore this area further, because
it might be something deeper which you have long supressed or not
known about.
