So, the legal framework in Oregon for psilocybin-assisted psychotherapy is actually still in development (and is experiencing some significant issues) - unfortunately, you can't count on having safe, legal access to professional resources there quite yet. Ketamine clinics have been cropping up in Oregon, however, which may be a useful treatment to consider in discussion with your mental health providers - many folks have found some relief from the symptoms of trauma, freeing up the capacity to work on the underlying issues in the long term.
We're very sorry to hear that you've been labeled as "drug seeking" by folks you've worked with in the past. That type of stigmatizing treatment by mental health professionals gives the rest of us a bad name, and we know you are not the only one who has not sought out treatment because of fear of the people who are supposed to be there to help them. Plenty of psychiatrists and others working in the behavioral healthcare field have not been exposed to all the excellent research that has been happening in this field in recent years, let alone received training that would enable them to have an even-handed, nonjudgmental conversation about their use. We would advise coming in prepared with your research before speaking with your doctor. If they are not prepared to treat your interest in exploring these other treatment modalities in a nonjudgmental, professional manner, that may mean identifying someone who has received more education and training on these subjects in your area.
