I'm boring

So i have one more problem aside from not having a baby yet.. I think i have social anxiety. Everytime me and SO goes out with his friends or family members, i always feel that i'm left out, that i am so boring to be with, i don't have sense of humor and i always feel inferior being with them. And i hate those feelings. I wish i am more like my other friends who can talk with people smoothly, no awkward moments.. So everytime there's a plan of get together with his friends or family, i always wish that it will be cancelled.. I know it's not good. I wish i have a way to overcome this. My social anxiety is ruining my relationship with his friends and family..😯😦
