Help identifying my weird symptoms? (most likely autoimmunity related)

I'm a fifteen year old girl, and I've never been in an accident, needed surgery, needed medication, or had some type of hospitalization due to an illness or health problem. I've been tested for a whole alphabet of stds, had blood work done, and undergone various MRI's and whatnot, as well. 

I used intravenous drugs, and overdosed on antipsychotics before, but I had all my strange symptoms before I started abusing any drugs for that matter. 

My diet is specific to my blood type, gluten tolerance, glycemic index, and BMI. I was raised with ultra-health conscious parents. I have not fed my body so wrong, nor exposed it to anything very dangerous. 

I was also raised in a house with cats, dogs, rabbits, and other animals, as well as flower pollen, average amounts of dust, etc. I don't have any allergies to the mentioned above, however I am "allergic" to cold temperatures. VERY allergic...cold urticaria....

I have had all required immunizations, and a partial immunization of Gardasil. (parents believe my auto-immune-like symptoms are linked to the terrible adjuvants in all those injections)

I have had most, if not all of my symptoms since I was at least seven years old. 

SYMPTOMS: 

1) motion sickness (couldn't even play on swings as a kid)

2) juvenile rheumatoid arthritis-like symptoms, but I was blood tested and I apparently don't have it. 

3) swelling of joints, and constant pain...especially in morning ^^ (arthritis yadda yadda) 

4) "falling asleep" limbs, every night, all the time, even in places like my crotch, and nose/cheeks

5) burning sensations in the heels of my feet

6) constant tiredness

7) constant aches and pains, everywhere... (especially back, knees, shoulder)

8) over sensitivity to light and sound

9) frequent headaches

10) restricted mobility... by that, I mean I can't run, jump on flat surfaces, basically... it hurts too much to do more than ride on a bike.

11) poor bone density

12) fatigue 24/7 

I don't know what started my problems, but they definitely came early in life. My drug use certainly hasn't healed my problems, but everything feels better on a heroin high. Please don't preach to me about drug abuse. I'm in Drug Court. I hear enough of it. 

The first symptoms to emerge were probably aches, pains, and juvenile rheumatoid-like symptoms. I have auto immune issues in my blood line. Both my immediate aunts have Fibromyalgia and Multiple Sclerosis...well I mean they both have auto-immune diseases... one has MS and the other fibromyalgia. 

I have been to the doctor many times to address these problems. Everyone is convinced I'm either faking it for some personality disorder satisfaction, or I'm a hypochondriac. As mentioned above, I've had blood work done, and an MRI. Nobody has anything to say to me. My pain is real. I don't want to end up authentically bed-ridden before it's too late. 

Does ANYONE have any suggestions? Advice? Comments? Aid? Similar symptoms?
