Formulary Madness (I am so ticked)

I thought that the biggest problem that I was going to have with Medicare Part D was just getting through the sign-up procedure. Not so. I got my card and packet from AARP MedicareRx Plan today. Two of the drugs that the formulary on Medicare's site said were offered by AARP are not listed in the packet that AARP sent me. So, I carefully examined Medicare's site and made this decision based on incomplete information. I thought that I could get three drugs (rather than the four I had been taking) for 70 some dollars. Instead, the plan will cover 2 for around 50 dollars. I am so upset that I think I'm just going to stop taking any of them. I'm confused and scared. My therapist was wants me to get a job, and now it's getting so expensive to buy medicine. I just want to shut down and not listen to anybody, curl up in a ball, sit here in my house and type lists of things. I'm scared. I don't know what to do.
