- After years of wondering why I struggled with things that seemed to come easily to others, I finally have answers. Being diagnosed with ADHD as a 46 year old woman has been genuinely life-changing—I finally understand why I am the way I am, and honestly, it's brought me so much peace. From start to finish, the process was straightforward and far less daunting than I'd anticipated. Response times were prompt, so I never felt left waiting or forgotten about, which really helped ease my anxiety.
