((((Sweetie)))) I have cried when getting pulled over. I felt horrible and embarrassed. They see that all the time. I am so sorry that happened to you.
And btw...it is your friend that should apologize to you for speeding and creating an unsafe situation for you while riding in her car, which is bad enough in itself.
The police officer may have taken her out because she was driving wayyy over the limit, erratically or in dangerous conditions. Or simply looked suspicious. Or has a record of speeding.
OR he didnt want tp scare you further. Did he ask you what was wrong? Did you tell him you are a crime victim and fearful of weapons? Did he ask your "friend" why you were so upset and she backed you?
It is not your fault. Remember you are working on these issues and are doing the best you can
