Hey girl I know how you feel! I had the same doctor for 18 years. He completely dismissed me. I too have had other diagnosis’s ( depression) that I thought were complete crap. I just stopped going to doctor and felt helpless. Then I started reading up on adhd. I read multiple stories from a variety of news sites. I said I know I have this,especially when I read about hypersensitivity associated with it! I looked up a doctor who specializes in that diagnosis! Made an appointment. At the appointment I took several tests and had a lengthy conversation with him. I found out I was at the severe end of the spectrum! I felt so relieved! I was 39 when I was diagnosed. Like so many I often wonder how my life would have been different if I just seen someone earlier and fired my other doctor. I hope this helps you feel not alone!
