Gotta get a doctor's referral, make a million phone calls, check with your insurance company, get on a waiting list over 18 months long, meanwhile your therapist says "you definitely have ADHD" but her opinion doesn't matter and she won't help you out until you get the official diagnosis.

But to get a bipolar diagnosis all you have to do is walk into the clinic and ask for an evaluation and get a 30 minute chat that day, then boom, you have a code in your file that says you can get help for that problem.
