WTBH, one lesson that came out of this for me is that if I am ever arrested the 1st words out of my mouth are going to be 'I want a lawyer'. As soon as you say that they aren't even allowed to ask you questions.
Second thing, was the officer talking to you in an interrogation room? It so there should be tape of the whole thing.
You have every right to be afraid but as I learned in the Marines is that bravery isn't the absence of fear, it is carrying on in spite of the fear.
Hang tough, I believe you will come out of this a much stronger person.
Your friend,
