Adderall and depression anxiety

Hi,
I just turned 25 years old, and was diagnosed with ADHD as well as anxiety after taking an EEG about three years ago. Before that time, I had been suffering from depression, anxiety, and I couldn't control my ridiculous cravings for sugar and carbs. I know that this sounds weird to people who do not have ADD or ADHD, but for those of us who do, these symptoms might not seem so odd. I had been in counseling and seeing Psychiatrists from age 15 on. Finally, I developed a terrible eating disorder due to not being properly medicated. Some deal with their issues differently than others, but I needed to feel in control of something in my life. As it was, I was completely unorganized, unable to focus on any one thing, unable to study and recall information, tired, unmotivated, and eventually Bulimic/Anorexic. Once I was forced to go to an in-patient clinic for a month and a half, I learned from numerous tests and great specialized doctors, I was finally able to start living again. At age 22 my doctor, at the time prescribed Adderall XR and Xanax XR and three years later, I am still taking both medications. I admit, sometimes I don't want to take it, because I like to feel my emotions and be in the moment of life, but I know without it, I am a wreck and completely out of control again. I let things go, become a total hermit, sink into my own pool of sorrows, and am not anything resembling my old self. Just one problem though, I am a singer and find that when I take my Adderall, I am so dry that my range is cut short- very short, and the tone of my voice is dull. I sing for a living, so this is a major concern. I also find that I don't seem to have the same emotion when I am singing. I can handle the emotional thing, but you can't hide not hitting the notes! What can I do? Is there anything to counteract this side affect? I asked my doctor and she said lemon drops- well, if you are lucky enough to find lemon drops- that's great, but they definitely don't do the trick. I drink nothing but water all day and still- I just can't stay hydrated! What am I going to do? If anyone has any advice or is experiencing the same problems, please drop me a line. Thanks so much for reading and take care!
