How do i talk to my doctor about bad anxiety?

How do I talk to my doctor about bad anxiety?? Im unable to drive certain places or do certain things alone and it's been effecting my work and relationship. I don't have many friends nor hang out with them cuz I have anxiety so bad . I get an uncontrolled nervous fèeling when it comes to doing anything alone like going to grocery store without my bf or going to the beach alone . I have taken some benzodiazepams in past that have worked good controlling those nervous thoughts but how do I convince my doctor that I want to try those types of meds again? Now that I'm only on birth control and ssri, I'd like to try benzos again. I feel lost and don't know how to talk to my doctor. Any help is appreciated!
