Am I getting depressed from being unable to get pregnant.?

I cry at least once a week wishing i could have a baby. I feel alone because i feel like i cant really open up to anyone or seek medical help because of how much $ its going to cost and also because my husband doesnt seem too supportive about the doctor. He wants to keep trying but its been almost 2 years. I havent been cleaning my house lately and i hate cooking (which i normally love to do) and i stress a lot at home. I feel happier at work. I want to eat healthy and lose weight but have no motivation to do anything. I just want to sit and do nothing and mope... i know that sounds bad and lazy but i cant get out of this rut im in....
