I agree with the previous posts. It sounds like it could possibly be ADHD, but you'd need to be tested to be sure. I've had ADHD since I was 10, so I know what it is like to be distracted consistently. But finding various activities and resources can help you stay focused and keep everything in check. Also, I've never been on meds or seen a psychiatrist, but I can totally see how they would be beneficial.
In any case, seek counsel where you need it, and do what your comfortable doing. Try not to worry too much, ADHD is a very liveable disease no matter where you are in life. Just be sure to take advantage of the resources and support available to you.
Best of Luck!
