Hello Postalacc;
Take heart!! Those of us who seek professional help - for help's sake alone - are those with the very best chances of getting our illnesses in-check; overcoming the seemingly insurmountable odds and regaining and happily maintaining our lives in the fullest way possible!
I think that we can all agree that anyone who can claim to have you diagnosed in a ten-minute, or even a one-hour session is very much mistaken. It sounds to me like the doctor doesn't like his job - maybe has grown cynical over the years. The symptoms you describe sound very disconcerting, and are affecting your life in an immeasureable way. It seems obvious to me that you have some illness working against you. Gezebel's advice is right on - you have to get yourself to another professional who will take the time to get to know you, and put to use all of the diagnostic tools and abilities (s)he has at hand. Also, Elisha gave you some good advice when she suggested that you read all that you can - especially regarding anxiety and/or mood disorders. One site in particular that gives a good layperson's explanation, and one I use quite a bit, is The Mayo Clinic Health site, at www.mayoclinic.com . It's very user-friendly.
From my experience as a student of psychology, I can point to some disorders that may be of particular interest to you - based on the symptoms you described. But, I can't stress enough the importance of getting a proper diagnosis, from a proper professional. You might look to some of the mood disorders, such as; generalized anxiety disorder; seasonal affective disorder (are your symptoms worse or triggered in any way by the seasons?); intermittent explosive disorder; bipolar I and bipolar II (esp. rapid cycling); schizo-affective disorder; schizotypal personality disorder; anti-social personality disorder; borderline personality disorder; the list is long indeed. Beware of 'student-syndrome,' wherein one starts to see certain symptoms in themselves and/or in close-friends or loved ones. We all have a bit of this or that symptom of some disorder if we look hard enough for it. That doesn't mean it's a life-affecting problem. Also, quite often, two or more issues can overlap at certain points, making diagnosis all that much more non-D.I.Y..
Just one other thing that I want to note; we have to think of how we present to a doctor. He has to like you to want to treat you effectively, and he has to WANT to treat you, if you are to get anywhere in moving forward with treatment. Often a doctor will test you in the manner that you described. If you are referred to a community mental-health clinic, that is exactly the place to get started on finding the right therapist, and perhaps (quite likely) a psychiatrist that WANTS to help.
Try to put yourself in the doctor's position... for example; if I was your doctor, I would ask myself some of these questions: What does he stand to gain - if anything? Are there unsettled issues in court that would benefit from seeking treatment? Would there be any financial gain for the patient? Does he present as humble, honest, and earnestly seeking help? Is he on-time for appt.s? Is he ever absent without good reason? Keep in mind that without medical insurance, you may NEED to use the Community Mental Health Clinic in your area. It's also as good a place as any to get started from.
I wish you great sucess in your journey toward enlightenment. I'd like to leave you this quote, that you might read it when things seem at their worst.
"Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men of talent. Genius will not... The world is full of educated derelicts. Persistence and determination alone are omnipotent. The slogan 'press on' has solved, and will always solve the problems of the human race." -Calvin Coolidge
One thousand blessings to you and yours, Postalacc, ~J
