Late diagnosis and relationship issues

I was diagnosed in my 40s, didn't realize that all my struggles were stemming from this. I was only diagnosed with dyslexia as a child. I believe my mother is undiagnosed. My childhood was good but very chaotic. Anyway, I struggle with relationships, my partners all lose patience with me and say being with me is like being with a child and I am not dependable. I cannot change my brain. I just ended a 10 year relationship and I am terrified to get in another. I feel like I only bring stress amd chaos on anyone I am with. Does anyone feel this way?
