High cortisol - nothing working for weight loss. Help wanted.

Hi, it's my first time ever participating in a message board, so I hope I'm doing this right. After 8 months of strict exercise and healthy eating I have lost 0 pounds. My doctors are officially "stumped" - their words, not mine. I'm just extremely frustrated. I'm wondering if anyone out there might have some ideas, thoughts or experience that might help provide a new direction towards weight loss results for me. Any help would be appreciated, so here's the facts (though quite long, *apologies*) of what I've been doing the last 8 months and medical history that is relevant. I'm putting everything out here in the event it helps someone connect the dots.

- 2007: constantly ill with head colds, sinus infections, eyelids would swell with red rash. Diagnosed with allergies to dust. Starting taking claritin, zrytec in the morning with a benadryl at night to control allergic reactions.

- 2009: my weight got out of control (reached 245lbs), had pain in right flank & was diagnosed with fatty liver. Experienced severe memory loss due to high levels of ammonia in my blood. I routinely was tired, with muscle/bone aches, my hair would fall out and nails would break/tear. My skin look pretty crapy too. Started P90X, followed the P90X diet and completed 3 rounds losing 55 pounds bringing my weight down to 190lbs. Healthy eating habits were established (lean protein, low complex carbs, high veg) plus I started taking vitamins regularly (B complex, multi-vitamin, iron, k, d, DMEA). I couldn't break through plateau of 190lbs.

- 2010 through 2012: couldn't lose weight despite trying different exercise programs or varying my diet. Weight would range from 190 to 210 depending on how often I would exercise. I could never get lower than 190 though....

- Continuing to feel like crap, in March 2012 diagnosed by blood test with celiacs (on gluten free diet since that diagnosis) - felt amazingly better, dark circles under my eyes were gone, things were looking up but my weight did NOT budge.

- In July thru August 2013 I tried a extra low calorie diet (Bob Harper's Jumpstart to Skinny) to break through the plateau. It worked and I lost 15 pounds eating 900 calories a day. I went from 200 to 185 breaking thru the 190 barrier for the 1st time. However it went back to 190 in 2 weeks (even though I continued with proper diet and exercise as the book recommends.)

- December 2013 proved a busy month for me work-wise and I let my exercise lapse by January 2014 I had gained 20lbs in 4 weeks. My food had not varied greatly from what I had done previously, just lack of exercise.

- January 2014 @ 210lbs: determined to fix my weight problem once and for all I planned to leave my job in February and focus 100% on diet and exercise. In january I focused on a daily workout schedule of 45 mins per day with a diet of 1350 calories. Once I left my job (and for the next 7 months I did 30 minutes of P90x3 plus 2.5 miles in the morning (before breakfast) and 2.5 miles in the evening after dinner. I'd add in yoga and pilattes plus step 3 times a week.

- I had my RMR done in April 2014 and it determined an optimum calorie intake of 1350 to 1550 for weight loss. I continued with my gluten free, 40% protein, 40% carb, 20% fat diet.

- June 2014: after not losing weight my doctor ran tests for hypothyroidism. It came back within the "normal" range but because I had numerous symptoms of hypo, she put me on a low dose of levothyroxine to help my body convert T4 to T3 optimally to help weight loss/ metabolism. I feel better on it, have more energy.

- By August 2014 I had lost 0 pounds. It seems my body is not converting fat stores and muscle growth is not significant (no matter how many squats or push-ups I do).

Further testing commenced and here are the results: cortisol is high, cholesterol is fine, no diabetes, liver is good, and I have low blood pressure. Dexamethasone suppression test for Cushings came back negative.

I don't know what to do now. Do I try working out 5 to 6 times a day? Do I try a riskier diet like that HCG stuff? Is there some secret to boosting your metabolism that I haven't tried yet? Is there something medically going on that the doctors are missing?

Any help or insight is appreciated. If you made it to the end of the post, THANK YOU for taking the time.

I'm so desperate to be healthy, happy and active. I miss running around WITHOUT the 55+ pounds of additional weight that's on my body. Prior to the age of 25, I maintained a healthy weight of 135 and a six pack (good muscle tone). I so want to return to having an active lifestyle and this weight just keeps dragging me down.
