rm,
Good Eveining. I like the way you have worked through your issues and I agree you may have the answer to your insomnia. I am wondering if you experience nightmares? I do and this is scary for me as I hate the feeling of reliving the traumatic event. I wake up and sometimes can be in tears.
You may often feel "too wired" to sleep. Your nightmares may be so alarming that you become fearful of sleep. You may associate darkness with danger. Being left alone with your own thoughts, without the distractions of your daytime activities, may prompt memories of the trauma which make it difficult to sleep. Coffee or alcohol may interfere with your sleep like never before. Persistent insomnia or awakenings during the night could also be a sign of developing depression.
Please do talk with your therapist as I know from my own experience how awful it feels not to be able to sleep at night when everyone around you is sleeping soundly.
Blessings,
Kitt
