serious P.P.D with hints of divorce.

I have recently become a new husband this past year, and my wife and I just 7 days ago had our first child. Durring my wifes pregnancy, she says I started to "drive her crazy" , I explained to her that its because all of the changes her body goes through when a woman is pregnant, but I will be there for her. Althought I had to put up with the typical "I dont like the way you smell" "get out of here" attitude.. which was nothing, I expected it, not to say it was easy, but we managed. I also had and am continuing to have issues with language. Let me explain. I am American, my wife is Dominican. I dont speak 100% Spanish, and she doesn't spek 100% perfect English, again, I understood this when we got married, it didnt seem to be that much of a big thing, after all, love is a universal language, all understand it, besides, we understood eachother perfectlly, albe it broken Spanish struggled to understand broken english, life was perfect. Fast forward to now, as I said, she is Dominican, and their are, lets say, certain traits of this ethnicity, that I have had issues with when it comes to my daughter, I dont know, maybe this is just my wife and her family, but for one thing, they talk LOUD! when my wifes mother came to see our 3 day old baby in the hospital for the first time, she picked it up, got overly excited and startled the baby enough to where my baby opend her eyes to see what all the camotion was all about, THEN, she said, "oh. mira. look her ojos are open!! MIRA TU MAMI< MIRA EVERYTHING!!!!!!" I mentioned to my wife, honey please tell your mother to soften her voice, so my wife did, and her mother said "No Importa!" which means, its not important! that totally pissed me off. she continued to scream, ahem,,, i mean "talk" to the inquisitive child as long as she liked.. fast forward to me and my wife alone after this adventure.. my wife says to me , "You KNOW how momie is! She can talk to our baby anytime she wants to! you have to understand that thats how se is." while not understanding that my main concern is for my new born daughter. It seems like her mothers hyper active loudness trumped daddys worry and concern, and that daddys worry and concern for his daughter didnt matter. Daddy has to understand in all situations. The tention my wife seems is only between her family and mine. I told my wife that I have a problem with anyone talking loud to our baby. I dont want the baby to be startled, or scared. My wife has seemed to grow ever tired of my input. I mention little things like, "Honey, the light bothers her eyes, can I turn it off, and she yells at me "NO!" right infront of the child. have made a pact with myself, Never to raise my voice infront of my daughter, to be a good example, but mommy doesnt seem to care about it,, again probably referring to her upbringing. Im soo frustrated because she now says, "Wait until I am healed (from her sasarian incision) then things will be diffrent, she says she will leave me, and take the baby to her mothers house.. she says she doesnt want to leave me, but "im tired" she says. The other day we had to take the baby to a pedeatrician, and set up a follow up appointment. The dr, said he is concerned about her anxiaty, and the DR, wanted to see me with the baby alone in a week. My wife would have none of it. She says she is going with me. so now we have trust issues.... please help me, my marrage is in shambles, my wife is too proud to get any help, ie.. couceling, even if I go and its under the guise of family counceling. My daugter is only 7 days old. I dont want to loose my marrage or my daughter. what do I do? My wife has shown serious jeliousy to my mother also..... everythings a mess. I dont know where to turn..
