Delaying- conversion

I am currently a chrisitan who is a minor though I dont believe in the religion because I know islam is the truth after proper research, and I wish to follow my newfound faith. But I know my familly will not take this well as they are very religious people. Should I delay my conversion till I am older? This means Ill be forced to take part in christian rituals and traditions which I dont believe in but then again it doesn't feel right delaying my duty to Allah. What should I do?
