Scrying may be an option of divination for you.
I'll assume you are young, so your parents are restricting you from purchasing a pendulum or tarot cards. So I'll also assume the use of candles and incense are also restricted.
But they may not mind too much if you ask for, say, an inexpensive black bowl. Pour in a bit of water, and there you go.
There are so very many different forms of divination.
You may also use bibliomancy: take any large volume, open to a random page, and place your finger at some point. The word or passage there would supposedly relate to the question.
Some people will divine using clouds.
And if you want to be clever, you can ask for a sand pendulum. They're intended as a desktop art: The pendulum, suspended from the top, hangs just to the top of the sand. Swinging the pendulum creates interesting patterns. But you could remove the pendulum for divination use, and you'll have a nice place for it when you're finished.
Or you could make a pendulum. Or learn cartomancy with playing cards in stead of tarot. Or cast stones, creating your own grid and gathering your own stones, twigs, and other bits which may have significance to you. Or you could saw discs from a branch, and use a marker to create a set of runes (or whatever other symbols you wish to use for the purpose).
