Wives family disturbing me inlaws harassing us what to do

I am only son & my Mom & Father lived in Village since last 10 years after my marriage because of un-understanding between wife & Mom. Yesterday my father & MOM visited at our home, in our family dispute, My wife got miner injured in late Hours. But unfortunately we didn’t notice because of night & I settled the quarrel. My father & mom need to go to the village in morning so I dropped them at railway station @ 5.30 AM & come back at home & got busy to ready to office. My daughter told me that Mom kurta is blood spot & samultasnly I got called from my SALA that he is coming. My In-laws( Father & his two son (one is Lawyer)) came & started Quarrel with me. He make a video with my wife that I wounded her & used to ask them dowry (CAR) & they threatened me for legally consequences. My wife is with me after our relative force for compromise, but now I am totally mentally disturbed & in fear & feel to committing suicide because of them. Kindly guide me
