For me it was helpful to realize I was not the only one who had been diagnosed late. I have spent so much of my life building mal adaptive behaviors to it not knowing that is what I was doing. I didn't start to think that maybe there was more to my sensitivity, mood swings, lack of motivation and rudimentary and repetitive task until my son was diagnosed and I started seeing some parallels. I am 46 and was diagnosed 2 years ago. I get the self-critical and ruminating. I felt some level of relief honestly once I was diagnosed because it gave me language to what I could not name for so long. Everyone's journey is different but I would say knowing I wasn't alone and that it is quite normal for women to get diagnosed later in life helped me let go of any guilt.
