Depression...

My depression is at it's highest right now... I have roughly 5 weeks until our baby will be here and my relationship with my fiance is deteriorating. He says he leaves everyday for work mad at me and goes to bed mad at me every night because he's not happy. Our money situation is just too much. My heart hurts all the time and I don't know what to do. We used to never ever fight and we used to laugh constantly but now it's like it's a chore to have fun...I am so lost.
