Beside myself... vulvar swelling when standing up and pain

i know ive been posting alot on these forums... im just so desperate for help! :(. i am at a point now where i cant walk around or stand up for too long without pain. its like all the blood rushes to my vulva and swells up. when i lie down my clitoris sticks out more than it used to... but is a normal skin colour. after standing up for a few mins it turns almost a purple colour. and my vestibular bulbs swell, and bulge out on one side. i am beside myself because the specialists in NZ have all told me to see a psychologist because they think this is in my head. but it isnt, and i know something is wrong. if anyone has had any of these symptoms please reply :)
