How could Adderall and drugs in general affect me later in life?

Please don't take offense, but most people cannot diagnose themselves with ADD. What you need to do is see a psychiatrist who can help you. From what it sounds like to me, you are more anxious than ADD. Anxiety can sometimes have similar symptoms of ADD. For example, it is hard to pay attention to things when you're worried about something else. It seems like you are feeling very overwhelmed. If I were you, I would definitely consult a family practice doctor or a psychiatrist. As far as adderall goes, it is a very serious medication and is highly addictive. There is still a lot of research going on in regards to the long term effects. Seeing as you have recently struggled with addiction, you may just be trying to replace one addiction with another. The best thing you could probably do for yourself is relax and work on your study skills rather than seek out a controlled substance. You said that you think doctors are really just licensed drug dealers... That is quite the generalization. While there are some doctors who would rather keep their patients doped up as opposed to dealing with their patients, there are many good doctors. Even after med school doctors go through a lot of continuing education and are required to retake their board certification tests. Think about it: many doctors are healing wounds, curing cancer, and fixing broken bones in order to help people whereas drug dealers just want to make a profit by convincing people to harm themselves.
