Saorean,
fleeing your country will not be an easy thing to do. From building new connections, to getting the right job , to housing, to country rules and customs to getting used to the weather.
maybe you can move away from your area first and see how it goes.
taking a drastic decision like that has its repercussions too.
religious persecution it’s not normally associated with Jehovah’s Witnesses, so that’s a dead end.
in my opinion if you still feel that you need to leave for whatever reason you need to, then you must sit and plan your life first. A legal plan though. If you have skills then look at countries that need those.
Leaving everything that you ever known behind is a gut wrenching feeling that will follow you for sometime. And if you would be leaving wouldn’t you be away from your family anyway? So your relationship would be almost non existent, like if you left the jws (not the same but very similar) specially if you are in Africa and flights can be expensive to the countries you’ve mentioned.
Is this something your family could do often? Go and visit you?
I understand that you are still young, so explore all avenues before committing to something that can turnout much harder than it looks.
Good luck.
