My stutter is subject to whom i’m talking

My stutter is subject to whom i’m talking Hey guys, i’ve been stuttering for quite a sometime now(since aged 12 now i’m 25). An interesting thing about my stutter is that it becomes bad and good depending upon the person i’m talking to. Like if i’m talking to my father or some high profile person or someone important or in a group, my stutter is worse but when i’m with my friend or alone with somebody my stutter improves. I know it’s anxiety factor but any suggestions to remain calm in situations when it matters the most. Moreover i’m a medicine graduate i struggled enormously through my medical school and now i’m starting my internship in two months where i have to engage with hundreds of patients daily, this anxiety is holding me back.
