Four or five years ago I went to clinic specifically for pain management and part of "my plan" was to go to a psychologist that specialized in chronic pain. I don't have anything negative or positive to say about it, I just didn't get anything out of it. This was through a HMO so seeing the psychologist was not to be a long term treatment option; she introduced various things to me that were not to eliminate CP but techniques to deal with them such as , biofeedback. I also got the feeling that the clinic's goal is to try everything to avoid long term use of pain meds (which makes sense), but alas over a decade later, here I am, on pain meds. Her specialty was cognitive restructuring/positive thinking with cancer patients, she showed me statistics that were impressive. I had a really interesting discussion with her once when I asked her for stats on CPers and stated, I can see how it works for cancer b/c two things happen, you die or go into remission, there's an ending either way, what's overwhelming for me is the endlessness of chronic illness/CP. With CP it's never ending, I'm going on 15 years plus of chronic illness and all this positive thinking is exhausting, maybe I should do some research myself and see what the outcome is for CPsers, if only I had the positive energy required (do I detect sarcasm?). Just as suggested previously, I would look around and try to find a match to your needs/situation and see what the therapist's goal or orientation is for therapy, some therapists do not believe in pain meds, for example. I see therapy as an adjunct to a current plan.
I'm a big supporter of therapy, I believe the right therapist can do wonders, the trick is to find someone you click with. There's a lot of loss/grief in chronic illness/CP so someone who specializes in grief, trauma could be good, not sure you necessarily need a psychologist specifically (and can be more costly). One other suggestion, there's a clinic in my area that specializes in everything to do with loss, mainly people who have lost a loved one to death, they do have grief support meetings (how to manage ongoing grief). Look in your area to see if a clinic like this exists, you never know, a support group could be available to you.
