Parkinsons' Disease - Right doctor

both my family doctor and my neurosurgeon both stated they believe I have Parkinsons Disease and being sent to a neurologist for treatment.  I do get intimidated by doctors and tend to shut down with intimidation.  I am in full agreement. as much as I'm not happy about it, that I do have PD.  I suffer 3 out of the 4 primary symptoms but a full list of specific symptoms I have also includes nonmotor symptoms.  slow to walk, blinking decreased where people wave thier hand and I can't blink, tremors mostly right side, but left side is now affected slightly too.  facial twitches at upper lip and upper left eyelid, neck twitches both back and forth fast and sometimes head will turn to left and tremor. I stammer and repeat words, i have to focus on writing each letter when writing and its real small compared to my normal handwriting which is large and nice. I loose my balance a few times a week and have fallen to the point where I fall and have been sent to ER. Requip helped RLS 8 years ago, and doesn't help anymore. My symptoms have been around for at least 5 years, but has gotten to the point where it affects my daily life. Can't put my own socks on, I've spilled drinks with the shakiness of my right hand and dropped peas and other food too. At rest, my body will actually tremor all over, stomache spasms with full body tremors, family doctor, neurosurgeon both believe I have this parkinsons disease, how do I get the nurologist to listen to that and treat me for it?  I did have electric shock treatments done about 9 years ago and was told by both the doctors, that caused brain damage.  My sleep study tests showed REM sleep behavior disorder which indicates parkinsons disease. I am constipated often and known to urinate 4/5 times in every hour which I don't drink alot either, sips of drinks during the day.  all doctors said that my medications I am on has NOTHING to do with all of said symptoms.  I have a hard time too with  my memory struggles esp when I remembered details of things. shoulder joint, right, is hard to move, pain there and rt wrist and elbow is also painful.  Driving was scary that I'd not blink and would cross the middle lane, ended up getting a flat while driving I had a full body convulsion, not seizure...mostly it was head facing left with constant twitches. I have copd, asthma, arthristist, and had lumbar laminecopy 6 mths ago, but was told this has nothing to do with that surgery and at my MMI.  Both docotrs have informed me not to work or drive and has put that into my medical records.  Used to type 95wpm with 0 errors, now I type maybe 40wpm with tons of errors. I loved to type, now I have to use the backspace. Its like I can hear myself think to my eyelids to blink, or foot push on brakes, but that doesn't work.  almost like my brain isn't attached like it used to be.  I also suffer from ptsd and under therapy for that and also to help me adjust to my illnesses as well as parkinsons disease, so I do have the support I need.  I am afraid of hearing the neurologist comment that it is all in my head when they hear I'm in counseling (for being abused and raped), doctors have isolated me and not listened to me in the past and this is too important to just brush it aside because the neurologist can't handle all of me.  How do I get the neurologist to listen to me when I go see him?  I plan to take along medical records stating having the parkinsons disease per my 2 doctors.  I just want to try some meds to see if it can help me get back some of my daily life back.  I've ignored the first 4 years of having tremors, etc., but now its to the point of having difficulty living. Please help.
