Shortly after arrival I decided that I had made a mistake.
What mistake did you make?
I just liked the place at first.  It felt safe, so don't judge me.
It's good to be able to admit that decisions we made in the past didn't turn out so well.  We all have to make decisions without knowing all of the facts, so if you don't like the way it turned out, it's fine if you want to go somewhere else.
Where else shall I go?
Well I am sure you have many options. Maybe you can ask someone for recommendations or look online to see your other options.
