Taking Valium For IUD Insertion?

So yesterday I went for an IUD Insertion (I'm getting the Paragard.) I had been very nervous about getting it and I have anxiety about gynecological things and I'm not sure why. 

Anyway, I got there and was called back to the examination room. I was okay until the point when I seen the large needle laying on the table with other things. I already knew I was going to get an anesthetic shot in the cervical area to help with pain but when the doctor came in she was in a bad mood, I was already nervous and she shoved the speculum in which wasn't very pleasant but I've had yearly exams so no big deal. I was very tense and she kept yelling at me telling me I needed to stop or she would hurt me unintentionally. She also asked my fiancé (he was in the room holding my hand) if I acted that way when we have sex. Then she stopped, told me I needed counseling and wrote me a prescription for Valium and I go back in a month to attempt Insertion again. 

My question to you all is: Will the Valium help me? And should I try to find another doctor? I feel like my doctor was very unprofessional with me and made me feel even more uncomfortable with the whole situation. I don't think I need counseling for being scared. Waiting a month is also very frustrating being I really need birth control. 

Thanks everyone ❤️
