Adderall Questions

I am a 3rd year engineering major in college, my work load is getting increasingly harder, and I find my self not able to concentrate (a problem I had since I was young). Along with internships, the work is overloading, and the fact that i’m not able to concentrate is becoming a real problem. I recently tried adderall from a friend, and I realize that it actually helps me concentrate and i’m able put full effort into the things i’m doing. I was wondering if there is any way to get prescription for adderall, and if I do get prescription for adderall, would the adhd show up on my medical record? I’m afraid if I actually get prescription by pretending to have adhd, it will show up on my medical record and cause future problems. Thank you all very much for the help.
