It took me about a year and a half to go from having a diagnosis to actually doing anything about it. Like it took my career going off the rails to take the diagnosis from the specialist to my family doctor.
My wife was skeptical at first, but now is very supportive. And to be fair it was about 10 years between my first inkling and the diagnosis so I suppose it's fair to say that I was also skeptical at first.
I'm now on my second medication and in counseling. I'd say it's only kinda working. The most effective thing has been to set things up to take advantage of urgency/accountability.
