Hi FVL,
I am incredibly saddened to hear about your nightmares and insomnia.
This is something I struggled with for over 10 years before I confessed my A. Every night I was plagued with severely anxious thoughts about my A, and at times I had full blown panic attacks.
A few tips that helped me:
- create a bedtime routine that tells your body "I am safe, I am going to sleep peacefully". Maybe drink some tea, journal, meditate, avoid noisy or negative distractions like TV/phones
- it helped me to have a positive distraction as I fell asleep. This could be white noise, or sometimes I would listen to The Sleepy Bookshelf podcast (a woman reading classic novels as bedtime stories to help you drift off to sleep).
- thought challenges: as you’re laying in bed trying to sleep, focus on certain thought challenges. An example is: name 5 things you’re grateful for or 5 good things that happened that day. Or think back to a location of a happy childhood memory and walk through that location in detail. Visit each room, try to remember everything you can down to the furniture, sounds, textures, etc.
However, for longer term, I think you should work with an IC on possibly reprocessing your memories and traumas. Maybe EMDR or brain spotting. This helped me quite a bit with flashbacks.
Also, utilize mantras. Intentionally write down some mantras to repeat when you have flashbacks. Things like "I am safe. I have come clean and I am living in integrity. I am doing everything I can to heal. I am committed to being a good husband and supporting my wife through R."
Good luck, I wish you both the best
