I have been considering for years now to go see a doctor or a therapist to help me figure out if I have adhd or add. I've noticed in my college classes that I will be the only person really trying to pay attention and focus while. I mean I am staring the professor down trying to soak in all that they are saying.

All of a sudden (BAM) daydream, and then im off the rails and there is no hope for my attention.

 I've also noticed that I have a hard time remembering big events all of my life. And that I have had really bad anxiety for a long time now.

My biggest issue is I feel stupid going to a doctor to have them check or that they will think I'm just being whiny or lying. 

Any advice helps
