Wife (non adhd partner) is unwilling to participate in treatment of my ADHD

The stress of our first baby landed us in a couple's psychiatrist, where I was diagnosed with ADHD. After being undiagnosed and untreated for 10 years, I can understand my wife's frustration. But her attitude reads as "I didn't sign up for this" and she does not want to participate or collaborate with my treatment. She doesn't want to go to therapy anymore and she is unwilling to read a single book on couples and ADHD (arguing she is doing her PhD and doesn't have time for that). I can feel she is burned out, and her unwillingness to participate is making me feel like divorce is inevitable (it's just a matter of when). Can I fix myself without her participation? Have others here succeeded this way?
