I'm 15 years old, and inconsistent eating is just one of my problems. My parents don't think much to do anything about it, but I'm getting really scared. For about a month now I have been dizzy to the point where when I stand up, everything goes black for at least 30 seconds, shaky to where I can't fill my glass the whole way without spilling it, paranoid to the point where the slightest problem could make me worry for days, irritable to where I would snap on loved ones, (I know, I'm repeating myself. Sorry!) I've been extremely thirsty, and I go days without eating until I stuff myself full and repeat the cycle. The reason I'm posting is because my dizziness is getting terrible, I fell today after standing up too quickly. And that isn't normal for me being a 5'3 115lb majorette.. It may also help to mention I've been diagnosed with ADHD and have been taking 40mg of adderall ever since elementary school. I don't think my medication is the problem seeming as to how I've had no problems until now. Please help!!
