I do not have problems with excessive nervousness, I have problems with anxiety. I get all panicky and mentally freak out and feel like I need to prepare for these things that are destined to happen to me.

It started when I started to become bombarded with legal proceedings, legal investigations, and feeling like I needed to protect myself from my ex because I was not able to get a restraining order.

The best way to do it is to just be completely honest. just say every single thing you're feeling without sugar-coating or changing anything — even if something seems weird or nonsensical. Your psychologist will appreciate the complete truth and then be better able to treat you. Not to mention, there's nothing too strange for a psychologist to hear — they're specifically trained not to judge.
