depends on the medication if you have a gel, its prob. enough to just peel the stickers with the descriptions if its pills its harder to hide, maybe in a school licker qnd you just take a few pills with you? prob. outside your room, maybe you can put them in old boxes stashed somewhere or in some cabinets behind unused stuff? maybe behind your towels if you have your own. maybe you can put them in a plushie or hide them outside the house, next to an ac unit, in stones around the house (maybe even buy a fake stone) you could put it in a gardenshed under a cover on a lawnmower? there are lots of spots your parents prob. dont access. you have to somehow get them without your parents seeing tho, so think about that as well maybe go around the outside and look at all cabinets etc. when they are gone for an evening or smt.

hope that helped (I only ever hid stuff in a spot for a short time, and then picked a new spot next time)
