Wish I could help but too old , diagnosed at 46 .
I am sure someone will reply soon, have you had a quick look at working age pd support groups in your area ? Might be worth contacting the organiser to check on age range attending.
Age is a number and you may find someone as old as 45😊 who has the same interests, challenges they face as your partner who has been newly diagnosed.
The support will be out there xx
