How do you keep confidence and hold frame when around people with big frame and big presence?

I noticed that when I’m around more quiet and low frame people, my personality flows well, I’m much better socially and my ability to make friends and meet women goes up significantly. But if there’s even one person with a bombastic personality or has a big presence or just effortlessly controls the frame, I find it very difficult to stay present and I feel like I’m losing frame and getting drowned out. And the harder I try the more desperate I seem. But if I don’t try then I naturally get out framed. Im not a big person, so I already physically don’t take up a lot of space.

My confidence and ability to socialize is entirely determined on who is around me and I don’t want my life to be like that.
