Hi Prisila.
You have a ton of advice here. All of it good. You can go through it and make your choice.
I have one thing to add that I didn't see posted or I missed it. You could have another person go with you or go alone and ask that your identity be kept secret in either situation.
I sympathize with your not wanting to stir up your relatives. It is a difficult decision.
Maybe one or more of the several here that voluntered could go in your place.
In any case it is a wonderful opportunity and I wish you and all involved the strength to carry through.
Best wishes to you all.
