Can't keep conversation going

With friends I can keep talk endless, but with family and the friend I can't talk with them , they aren't much of a talkers either, I constantly feel arond them that I need to say something its just makes the situation very uncomfortable. I worry that If I leave the house that I still don't have a good relationship with my family and probably will never go to them.
Its just so tensed around them, with my anxiety and say the wrong things (sometimes rude) I push them away.
Only with my mother is it fine

i feel like that with my distant family to:cousins, aunts & uncles....
i dont pay much attention to it though....
for me it is more important to get conversation going with friends &
acquaintances because most family members will love you no matter what while friends can just think you are boring & leave you...
