"Take me as example. I was born a Muslim. I didn't choose this way of life. And now that I want to change my life, I can't. I'm going to be a Muslim for the rest of my life."
Why? Did you sign a contract banning you from changing religions? (I know some Muslim countries have those, that's why I asked). Otherwise, if you are unhappy with that, nothing is stopping you from cahnging your life. Literally, nothing. You only need to want to and try.
