ADULT ADHD. Need of getting treated.

I think I have ADHD.I struggle alot with managing stress, time and important tasks. Whilst working on a relevant task I often find my mind losing focus on the task and thinking about other things. Through out my academic life I have been an ave rage student, but I remember my teachers/professors commending me for my work/ideas that I come up with, and I also believe that I am not any less intelligent than my peers and that's one of the reason I have made it up to Master's. My attention swings between the task and other things, so much so that I often stand up, stop doing the task and start moving until I eventually back to realisation that I have work. This terribly affects my productivity. Since I am student I have to read alot, but read is really difficult for me. Its really hard for me to focus and understand long pieces of literature. Whilst driving I feel anxious and often feel that I might ram into something and also visualise accident. I am in dire need of getting treated.
