Anna Dear!!! Please forgive me, I just thought of something that I had forgotten about. It should set your mind at ease...I wish I had remembered it earlier.There is a Betaseron Foundation to assist people who need help paying for their drug. They paid for mine for almost a year when the #$%^&* insurance company wouldn't pay. It's run by the folks from the drug company, Berlex, which makes Betaseron, and they are great people to work with. I assume there is a similar group with the drug Avonex. I would never have heard about it except that a technician in the doctor's office mentioned it. The MS Society probably has info for you.
The last thing you and Amy need to worry about is the #$%^& insurance company. There is a network of folks like me who can help you fight 'em.
