I am glad you are resonating with what I am sharing!
I would recommend a therapist or coach who works with co-dependence, gifted adults, and/or Narcissistic Recovery.
I work with people in your situation, through an online venue. I am happy to offer a free 30-min phone or Skype consultation to help us a get a sense if we could be a good fit. Feel free to write me at email@example.com if you would like to work out scheduling with me.
There are also probably people in your area, whom you can meet with in person, who specialize in this. Just do a Google search with the all these terms, “gifted adults” + “Narcissistic recovery” +“Treatment” + “co-dependence” + “(your location)”. This will likely yield practitioners you could work with.
I hope this helps!
