It’s nothing to be anxious about. I’ve been to different therapists when I was younger and started going again about 4-5 weeks ago because I needed it. It really is helpful if you put the effort in. First session is usually knowing your interests, basic info, significant life events good and bad, things you’re currently struggling with, goals you have for therapy. It might feel like the first couple sessions aren’t really going anywhere but you have to give it time before they dig deep into things and start diagnosing. Don’t get discouraged.The best thing is to be 100% honest. If you lie about anything you are just cheating yourself of actually getting the help you need. It’s okay to be wrong, it’s okay to make mistakes, it’s okay to struggle, they are there for you and will not judge you, they just want to understand so they can help guide you where you want to be in life. Good luck!!
