I swore that I had undiagnosed ADHD. My psych gave me the little questionnaire and my score was borderline. But I was so certain. Turns out, symptoms of PTSD (which is what I've been diagnosed with) can be similar to ADHD. Not sure how helpful this is. I can definitely relate to the frustration of not being taken seriously because it took over a year for me to be diagnosed with anything other than depression and anxiety.

I am going to get checked out for ADHD at some point this week. I'm 23, so I'll let you know if my anxiety/depression diagnosis changes
