When I was active in the now defunct annieproulx.com forum and in another one run by a guy in Eastern Europe, they were AMERICAN members of those forums who had let the movie and its message take over their lives.
I suggested that they find a licensed and certified mental health professional to talk to about the movie and how seeing it had affected their lives. Most of them gave stupid reasons for not talking to a psychologist, psychiatrist, social worker, etc.; and that was an attempt to claim for themselves, "I'm not that crazy!"
I told them that to keep mentally sane, most people need someone who does not even know people they know to talk to about what is going on in their lives. And, the help of a professional who is ethical is the best way to take care of that. Mental health professionals are NOT supposed to share with anyone else what a client says to them in confidence without a signed release form giving the professional permission to do so.
I did talk to Dennis, a VA licensed clinical social woker, after I saw the movie at a regular monthly session back in January about the movie and what I had read in the original story. Dennis is not gay; but, he does have an adult niece who is a lesbian. I have talked to him more about how the movie affected other people than what effect it had on me. (I have stopped the sessions because of the VA's budget being controlled by a Republican Congress and Administration, I was only being able to see Dennis for 20 minute sessions once a month. Because of the back log of new war veterans needing help and the government not providing funds for the people who had gone to war from them and need help, the VA just cannot do what it was created to do in the first place.
Other than the fact that most of my cyber-discussions are related to the story of Brokeback Mountain, in all of its forms, the movie has not taken over my life.
In fact, most of the issue discussions about Brokeback Mountain have been discussed in the various Yahoo Groups which I created and moderate. And, those discussions have been going on for several years now.
