My in laws are driving me insane!!

I'm so upset to the point I'm crying mad because of my in laws...I married their baby and I guess they feel like they have total control over my life...they come over unannounced ..call when THEY wake up and won't stop until someone answer..they dictate every aspect of my husband son life if they mad they coming at his son...like and my husband won't say ANYTHING ...He never stands up for me because he says he is never disrespecting his parents...like I don't even want to go to the family reunion today because of them ...what can I do ??
