Is Adderall suitable for treating depression, and how can I coax my doctor to put me on it?

I had been on Zoloft and Trileptal, but I got a deadly electrolyte imbalance. Also, along w/ the electrolyte/salt imbalance i went nuts. I was EXTREMELY paranoid as well. I deleted some friends from my facebook and was afraid kids at school were plotting against me. I accused my mother of trying to poison me (which was not true)! My psychiatrist (who falls asleep when i talk to him and has a smelly, moldy office) said it was a "manic episode" and put me on lithium. My school psychiatrist and neurologist said just stay away from those meds, b/c i had a bad reaction to them (and this episode would not have occurred under natural conditions). Also, the school psychiatrist thought the other psychiatrist was a moron for saying i had a "manic episode" caused by bipolar disorder. btw: i am getting a new psychiatrist. The neurologist said years ago that i probably have ADD as well (i have always had a "listening problem" and i can never complete anything i start). I also have tics, which i have been taking Haldol for for almost 10 years. i have always had trouble losing weight, no matter how healthy/much i eat or how much i exercise. To make matters worse, the lithium has caused me to gain like 15 lbs, and i am totally disgusted by that. My $200 juicy couture pinstripe jeans don't even fit over my blubbery thighs anymore! I am only 17 years old, and i am a size 8 (and only 5'4). I want to look cute and ii, but i feel i cant b/c of my size. I have been told (by a doctor and a few other ppl) that i probably have insulin resistance (and lithium causes that too). Nevertheless, if i cut my portion size not only will i probably not lose too much weight, but my metabolism will slow down; therefore i want the doctor to perscribe me Adderall. I can never concentrate on school work anyways, and all i do is goof off on facebook and the internet when i get home. In school, when we are asked to start clwork all i do is chit chat w/ other ppl or daydream. I heard it also helps depression, but i am afraid to go on it b/c of what happened w/ the other medications. Also, i have tics so i dunno if the Adderall will exacerbate that. Ultimately, the weight loss caused by Adderall will make me feel better about myself and that wil help cure my depression in itself (cuz i OBSESS over my weight). How the hell can i persuade my new psychiatrist to put me on this miracle amphedamine drug?
