Treating anxiety

How did you first talk to a doctor about your anxiety and depression? I’ve struggled since I was very young with anxiety and started having anxiety attacks before I was a teenager. Even though I could have been, I was never open with my parents about what was going on. Partly because I didn’t even know what was going on or why it was happening. Since I never got help obviously as an adult it affects me everyday and is pretty severe. I want to talk to a doctor but I get there for my regular appointment and never even bring it up.
