Some professionals say that psychological counseling is necessary, otherwise an ex-member of cult will have permanent problems. This leaves the people who live far from cult experts without any hope.
Reading Margaret Singer's works, I noticed that she had never stated that psychological counseling is absolutely necessary. She considered the process of postcult recovery as an educational process, and not as a therapeutic process.
Coming out of the cult pseudo-personality is about reeducation and growth. Self-help through reading can be invaluable for those who live far from knowledgeable resources such as exit-counselors, cult information specialists, former member support groups, and mental health professionals.
(Cults in our Midst, chapter 12)
This gives a hope to ex-members of cults who live far away from cult experts.
So, I think that ex-members of cults who are able to consult psychologists/cult experts, should do that. Those who do not have this opportunity should educate themselves through reading the literature on mind control, contacts with other ex-members of cults and so on. Through their doing that, they can solve their problems caused by cults.
I know some former members of cults who did not go to psychologists, but were able to deal with their problems caused by cults.
