Managing weight with an eating disorder- please help :(

Hi all,
I have had a long history battling eating disorders and my weight has fluctuated from 108-178 in the past few years. For several years I was able to maintain my weight but started drinking which led me down the path of binge eating that made me gain back 30 pounds. This past year has been a severe battle with the binge eating / restricting cycle. Since January I have lost approximately 15 pounds with a close, calorie counting diet of around 1100-1200 calories everyday. On top of that, I was exercising about 2 hours per day usually with an hour of elliptical / biking and an hour of weights. Some days I would add in an additional hour of running or biking, and 2-3 days a week I would not do strength training. With the amount that I have been restricting and training, I feel that I should be losing more weight. I have had many physical and mental symptoms that have worsened over the past few months, ie feeling weak, about to faint, fatigued, joint pains, foggy brain, forgetful, paranoid, anxious....you name it. Last week I had a severe mental breakdown / panic attack / dehydration scare with heightening of all these symptoms which resulted in a trip to the ER. I had to return home to family for nearly a week and in that week I binge ate and snacked on random food throughout the house. In reality, I was probably eating 1500-2000 calories a day which "should" have been sufficient to maintain my weight considering I was still over-exercising during this time. However, I can see noticeable changes in my body and feel like I have gained at least 5 pounds in one week. I am extremely depressed because after all of my hard work of losing weight (which has taken me months) has resulted in me gaining weight in just one week of upping my calories. Before the ER trip I was about 5 pounds away from my goal weight but now I am set back even further behind. I suspect that my metabolism has been screwed up from overexercising and not enough calories / protein and my hormones are all out of whack. I am in real need of a healthy eating plan that has the right amount of macros / calories and will help me lose these last 10 pounds and keep it off without my weight rebounding. My eating disorder mindset just wants to restrict even more, but I know logically that I could end up in the hospital again if I keep up what I was doing. I am already working with a psychiatrist and an eating disorder specialist but need structure in terms of my eating plan. Any advice would be greatly appreciated at this point as I am very desperate.
