I am mentally suffering from the marriage.

I got engaged to a girl with my will but later when I started meeting her I did't like her so I thought of cancelling the marriage & told everyone. But her family & she didn't agree this. My family took me to psychology doctor because I was avoiding marriage. The doctor gave me medicine saying that take the tablets for 1 month and we will decide late. Those medicine dried my feelings, I was always sleepy & not able to think clearly. During this girl family called us for the meeting there I told them that I am not feeling anything against her. I talked to in person and said same to her but she was not ready to cancel. She had told me earlier that they are gonna file a case against my family. So I had to say yes forcefully. I took those medicine until my marriage. After stopping the medicine I again started feeling bad & I don't like her & don't want to live with her. Now her family is threatening me that I have to spend life with her otherwise they will come to my house and fight etc. My family is scared and forcing me to continue. It's been 1.5 month since our marriage and it's been hell for both of us. We are not happy. But she is not ready to end because she has fear of society, etc. I am not able to live with her.
