husband influenced by family to divorce wife

My husband has been influenced by his parents to divorce me, we have been married for past 1 year, the marriage was against their wishes, but now husband says he is tired of living with me as I keep ill all the time and wants to divorce me. I have been hospitalized 10 times since my marriage, I myself dont know why I keep falling sick, even doctors aren't able to find anything abnormal. I have always been depressed since my marriage and my husband without knowing disturbs me a lot mentally, I was once admitted to the hospital on account of physchosis, now he says he will use that against me while filing for divorce, I am not mentally ill, Its just that he has tortured me emotionally and mentally a lot that I behaved out of my mind. I believe in marriage, its a lifetime commitment for me and I love him a lot too. I don't want divorce. I just want to know what if I am not agreeing for divorce, can he still get it by proving I am not fit to live with him? I am also afraid as I have been threatened a lot by some people that his lawyers will get you to agree for divorce. Please help.
