Tough question but interesting one.
I would move to a completely different place, new culture, new people, somewhere I have never thought of going and explore new things. I would try to give away everything of my past and lead a completely changed life. Make friends who have a different mindset from mine and learn to adjust with them. I would make myself more adaptable so that I can survive any similar situation in the future.
That will be difficult for me because I don't easily associate like that.
I do take my time to get friends
