Is it possible to go on a trip from England to paris just on my own?

You only live once, take an ipod, a few things to eat, a book/magazine and some money and go and visit another culture for the day. The train ride will be worth it if you really want to go. If you like doing spontaneous things, just pretend to your parents you're going shopping for the day but go to parris instead then come back in the evening with the great feeling of pride of what you've achieved whilst your parents don't have a clue. Why don't you take a friend just for good measure. But remember, be safe, because anything can happen. Enjoy and good luck.
