Adderall and anxiety

im 14 and take 50 mg of adderal a day for ADHD and Bipolar, and i am unsure of it. I weight 96 lbs.... and i am almost 5 1/2 feet tall... so i am very underweight... and i do notice that when i take it, after it kicks in i seem more aditated, and cranky, and i obvleisuly dont eat.. and my mouth is always dry. i am just unsure about the whole crankyness change after i take it... does anyone else seem more agitated when they take this meds and it kicks in.../ plz reply. thanks

I have been taking adderall 30mg immediate release twice a day for a little over 2 years now.
My hair won't grow. I have gone from a size 12 in women's to a size 0 in juniors. I am 36 years old and the bones in my face and body show through my skin.
I get very dizzy and I get anxiety really bad.
My toenails are paper thin as are my fingernails.
I have pushed everyone in my family away. I don't even play with my children anymore.
I am currently seeing a counselor once a week to help me with issues, which I hope will help me get off of this medication.
PLEASE DO NOT BEGIN TAKING THIS AS IT IS SO HARD TO GET OFF OF IT.
As another person stated, people I work with think I am on crack!

Hey,
My name is Krysten im 14 and im in the 8th grade. I'v been taking adderal for almost 4 months now. Before taking adderal I wasent doing good in school, I would always get into fights. My life was miserable. So I asked my doctor if I could try adderal agian. Before when I took adderall my stomach hurt and I wasent feeling the same. Then I wanted to give it a try. A week after I started to feel my self agian, my family and my teachers noticed a huge diffrence in my academics and my ADD. I went from getting E's and D's to getting on the honor role last quarter. I got the most improved in my grade and I was very happy. Now its the final quarter and now im feeling that adderal isant helping as much as it use to I'm worring about if I'm going to do as well as last quorter and im feeling a little anxiety. I went from taking 30 - 40mg in less than a month, Since I take 10mg after school. I also have been exeirencing weird things. When I get up from sitting down, I sometimes get a huge headach, I cant breath for about 30 seconds, I sometimes see stars and Its like a black out also, I get up then I cant see anything its all black, then slowy I can see agian. I would really like to know if i should raise my Mg higher for me to focus more and be happyer over time. I think adderal was a life changer for me. Please answer my question as soon as poosible!
