Is it normal to be so upset at your marriage?

I have been married only three months (I'm 24) and I can barely touch my wife. She belittles me and has to controle everything. She tells me I'm not a man, and that she married a pathetic person. She is always upset about something, then takes it out on me. I am a passive person, so I try to avoid arguments. So, I have basically become a huge pussy. To avoid getting yelled at, I basically shut down. I have tried to talk to her, but she just makes it about her. She then has either a pity-part or gets angry. I can barely get through sex sometimes; I don't want to touch her. Sometimes I can't get an erection and she has another pity-party ("you don't want to have sex with me, all other men want sex" *crying). I got so depressed I started thinking about doing something bad to myself, so I got on some medication. I can't talk to anyone because I don't want to talk badly about my wife. I need help!
