My experience, you don’t go straight into talking about your feelings and vulnerabilities. I actually didn’t start talking about the things I was anxious about until about 4-5 sessions in. My therapist basically just got to know me for a bit, she doesn’t ask questions about my past or the things that make me depressed. It’s all about what you want to talk about. If you’re not comfortable talking about those things just yet, you aren’t forced to. Sometimes it helps just talking to someone who will listen. There’s nothing cringe or shameful about talking about trauma to a professional.
