Mental harassment by in laws

I am married to a guy in UP. He is a very good husband and partner. But his family is harassing me and my parents since day 1. They always questioned about the money in envelopes given to them and relatives, and lack of gifts in the name of diwali. All the expenses of marriage were born by my parents. On the wedding night my brother in law got very drunk and didn't let my husband enter the wedding for 3 hours. Talked very back badly to my father. Because of the delay my whole wedding night got ruined. His sister even asked the gold earrings back gifted to me in muh dikhai ritual. Mother took all the gifts and money back. Even after the wedding his sister's questioned my character. I demanded an apology. But they haven't apologized till date. His sister's blocked my number stating they felt bad when I put up a WhatsApp status mentioning it is bad to ask for dowry (without mentioning anyone) It's been one and a half year I cry every night because of the flash backs I get from my wedding night. I and my husband are struggling to start a happy life because of the trauma. What should I do.
