Too Much Medication?

I'm really worried about my mother. She is 83 years old. She is heavily medicated.

This morning she is all upset because she doesn't have the pills and keeps saying she has to have them. Is she addicted to all of this?

I told her she needed to get off of some of the pills because she is very unstable with her walking, very moody just not herself.

I feel the doctor is just a pill pusher. Am I wrong? I'm so worried about her.
