It is possible.
I am 26, male, have had symptoms of AMN for 5 years.
I have a 32 yr old sister who is a carrier, but does not have symptoms yet.
It is fully possible for a female carrier to exhibit symptoms in their lifetimes. Males are almost always the ones who show symptoms, but it is POSSIBLE for females to have it.
In your case, I feel for you, and now we are both struggling together.
My best advice is do what I did: get a few (1-3) doctors to look after you, prescribe you drugs, make sure you're not getting really really bad too fast. Most don't have any clue what this disease is, but they can educate themselves. I take steroids for Addison's, anti-depressant for depression, pain killers for pain, and frequently see my doctors to check in for my health.
The best best best advice for a symptomatic patient is to have a close support network of people, because as this progresses fast or slow, they're going to lean on you really hard. They're going to need you. Show them deep understanding, deep love. Be their hero.
I hope all is well!
