cw: medications, discussions of addiction

I have dealt with problems with anxiety for over 10 years (GAD), and have been trialing medications for anxiety and other MH problems for about the same amount of time. Nothing's ever touched it, so I'm still in the process of trials.


I was prescribed a benzodiazepine for the first time almost a week ago, and it's helped my panic attacks (which have been getting progressively worse recently) immensely, it's easier for me to socialize, etc. One of my parents is an RN, and won't let me hear the end of how if I take a benzodiazepine, I'll immediately get addicted. I have a family history of substance use disorder, but I personally have never experienced addiction.


My doctor and I went over the "rules", side effects, etc. at length before she even would prescribe it, and she thought it was the best plan for now, but my anxiety about taking it has almost overshadowed the feeling of relief from anxiety I've been experiencing. I have a lot of medical anxiety due to bad experiences with medications in the past and providers invalidating my experiences with mental illness. The idea of becoming addicted to any substance is one of my worst nightmares.


I am legally an adult and have no healthcare proxy/I make my own decisions about my medical treatment, but I don't know how to deal with this anxiety associated with the idea that I'm ruining my life by taking medications as prescribed. I currently live with my parents, and I feel like I can't escape the fear because it's constantly reinforced, even if i'm not concerned myself. 


Has anyone else had experiences like this? I feel like I'm at a loss because of these conversations.
