false. the shariah already specified how to deal with apostates. apostasy isn't a right.
HOWEVER
after they are arrested, they get three days to recant. in those three days, they should be talked to and they should be called back to Islam. and insha'Allah during the three days, they can talk about things like their doubts and have their doubts answered and all that. the way they're dealt with is very humane wallahi. but in the case of OP, I think OP is just very young and impressionable. it is maybe just a phase and then they will look back and see it was just a mistake but they will be back on the right track eventually insha'Allah. Christians are leaving their religion in droves, even people raised in Christianity don't want to stay in that religion.
