Depression

Hi guys, basically I believe I may have some form of depression. I don't really want to go into the details of why and how I know as I'd be here forever, I've also done independent research on it and I correspond with all of the symptoms given. I'm just scared as to where to take the next step from here, do I need to go see a doctor and tell them how I feel? If so what do I say when I go and see them? I'm just stuck right now guys and I can't carry on feeling like this for much longer. Please someone give me some advice, thanks x
