Evenity and mental health

My twin sister started the evenity injections in Nov 2021. I started noticing a mental decline in her shortly after. She has completed the injections and I am very concerned about her. She is my identical twin and I know she has been severely effected, so that there is no way to make her understand. She and her dr say it’s her age and I know it is not. We have been able to connect about everything and this has split us. Any advise where to go?
