Embarrassed to talk to people

Embarrassed to talk to people I’m just wondering is it only me who feels completely intimidated at family dinners and never talks or speaks up as what I want to say I can’t. None of my friends have a stutter and they don’t understand how it feels so I don’t like joining in conversations because I don’t want them to laugh at me like I’ve been laughed at before. It stops me from being talkative and chatty and that annoys me.
