What Are The Symptoms Of ADHD?

I am 36 years old and I have been wondering lately if I may have ADHD or a form of that. Since I was a child I have always done poorly in school except for the class that I was very interested in. I always had trouble focusing even when I would tell myself over and over to focus and retain the information. I have always had symptoms of ocd where I feel the need to touch things a certain amount of times, move things in specific positions, and many other little quirks. I always feel if I don t do these things then something bad will happen. I will have to walk sometimes around an object in a certain direction etc. I daydream aimlessly most of the time and if I have multiple things that I need to take care of I usually cannot prioritize and focus, so I usually get stressed and shut down basically and don t even do the things I needed to. I will put my priorities off until I feel like I have a clearer game plan or I can do things perfectly. My brain feels like its in a cloud most of the time. I can sit in my office and stare out the window or get up and walk around or basically anything else to distract me from the things which I need to do. Not necessarily just procrastination, but more just in a jumbled fog. I have never really though to much about any of this other than I m just a daydreamer. My coworker has ADD and has recently told me that I defiantly have it. So now I m wondering if this is the reason I have always felt this way, or am I just trying to label something that doesn t really need a label. Any advice or insight would be appreciated.
