Giving up hope

I am simply just giving up on everything. This baby making is making me beyond depressed. I hate work because my co worker that I work with all the time is pregnant and I am tired of hearing about her pregnancy, it literally I swear to god feels like a stab in the heart every time I see her. I give up on my relationship with my husband, I give up with my parents because I feel like I can give them the news to make them happy. I know I should stay positive and all but I can't. I literally don't know what to do or how to thing, I am tired, unmotivated, and I don't want to get up from the bed in the morning.
