Hi,
@rab91 . The first time I told my therapist, I definitely was worried about going back. I was afraid of being judged, afraid I was wrong, afraid to betray my family, and afraid I was crazy. It's perfectly normal. All I can tell you is that it gets better. The first 6 weeks or so talking about your trauma and going over it with your therapist are the hardest. After that, you become a little less emotionally involved and re-experience it much less frequently, at least in my case. My guidance during this time would be to focus on self-care and positive thinking. I journaled like crazy during that time. Be aware that right now, you are forming potentially long-lasting perceptions of the world. As you recount your story, don't forget about the positive, safe moments in life, and make sure you mention them. My number one piece of advice would be to buy a DBT workbook, or, preferably, enroll in a DBT course. You'll need all the coping skills you can get, and will learn mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness, and will likely recover much faster. Be mindful of changes in your behavior; you may be tempted to isolate at this time. While you will need a ton of time to yourself, maintain whatever routines (especially within your social life) you can. Perhaps look up an emotion wheel so you can begin identifiying your emotions. When you say "freaking out," what are you actually feeling?
Finally, remember these are simply suggestions. Try 'em all, but keep the fish (what works for you), and spit out the bones (what doesn't). :) Best of luck, and let me know if you need anything else!
