Could My Difficulty Concentrating In Noisy Environments And Frequent Anxiety Be Signs Of ADHD?

I think i might have ADHD or something similar and i wanted some doctors advice on what i should do. reasons i believe this is the most obvious thing that stands out to me is when more than 2 people are talking around me or there are more than 2 noises going on around me i cant concentrate and i get aggitated and upset and feel like i cant do anything. i also get major anxiety in many situations and just dont know what to do anymore.
