It is always difficult when a young person goes off in a direction that will ultimately mean dangerous places and dangerous events.
I would ask this forum to include Nektarios in their prayers while he is gone on this difficult and potentially dangerous road.
May the Archangel Michael and your patron saint watch over you and protect you. May God confort and give solace to your family.
God Bless,
Milla
P.S. If you can take an icon of St John of San Francisco with you he his known to protect warriors.
