I think I have ADHD

I think I have ADHD After struggling all my life with focusing, hyper fixating on things, and stuttering, I came to the conclusion I may ask professional help to see if I have ADHD. I am not diagnosed with it, but most of the symptoms completly describe my situation, and since I'll soon start college, not beign able to focus and also stuttering, could really damage my career. Does anyone of you have both stuttering and ADHD? If yes, was medication helpful?
