Possible Adrenal or Pituitary issues? Video of pupils..

[KimPlus2]

I originally posted this in adrenal insufficiency but I don't know that that is what I have so I am posting it here as well..

My story is a long one, but I'll try to keep it short.

Starting on May 23rd I began suffering from daily panic attacks (when I've never had them before), severe dizziness/faintness when standing up (vision goes black for 3-10 seconds), extremely high heart rate (had a 48 hour holter monitor test done, no heart problems, just a heart rate that goes up to 165 bpm just when standing up/walking to kitchen which is not a long walk, it is normal when sitting down), excessive sweating (although it IS summer), thirst and urination.  I also get headaches that last for a couple days at a time on the top of my head and the left side of my forehead (very rarely on the right side) and fluctuating pupils.  My pupils fluctuate nearly all day long, but especially if there is bright light.  I did a flashlight test which showed even more fluctuation.

Here is a link to a video of my pupils:  http://www.youtube.com/watch?v=dIu1TI961XQ

I am female, 21 years old with asthma and overweight.  I had just lost about 35 pounds (from working out and eating healthy) when this all started to happen, and now it is so bad that I can barely walk around my house and take care of my kids, let alone work out with the vigor that I previously had.  I still eat healthy but am not losing weight.  About 1 year ago I had twins and lost quite a bit of blood but have since recovered.  (Not sure if this would help, just thought I should add it in just in case!)

My doctor thinks that I'm probably just "anxiety ridden" because I have twins but I am POSITIVE that is not the case.  He is not taking me seriously and that is why I am here.  I am currently taking 40 mg of Celexa and 50 mg beta-blocker atenolol and neither one helps my heart rate from speeding up.  On top of that I am taking 250/50 advair (have been taking for 2 years) and albuterol as needed.  Thyroid seems fine, B12 levels in normal range but on the low side so I am taking a supplement.  I'm wondering if this could possibly be a problem with my adrenal glands and/or pituitary gland?  I'm not looking for a diagnosis (but if you have one, I'd be glad to hear it!), I just want to know where to go from here.  If you need any more information, I'd be glad to share it.

Thank you,
Kim

IMPORTANT... I got this off yahoo about Celexa... note the last listing of serious side effects:
"Call your doctor at once if you have any of these serious side effects:

■seizure (convulsions);
■tremors, shivering, muscle stiffness or twitching;
■problems with balance or coordination; or
■agitation, confusion, sweating, fast heartbeat."

See dysautonomia forum for some replies!  You might also want to get your iron level, ferritin, and T.I.B.C. checked, even if your CBC shows everything in normal range, because I experienced low iron, normal CBC and was still very fatigued and my tachycardia numbers were higher than they would have been if I had not been low on iron.  For instance, my pulse was in the low 160s at the highest with standing when I was iron deficient and the highest I've seen it since I've not been iron deficient with standing is in the low 150s.
