Depressed and about to give birth

Anyone else get like extremely depressed right before they have the baby. Don't get me wrong I am sooooo happy and excited to meet my baby boy but me and my fiance have been fighting a lot and not b seeing Eachother much and when we do we hardly talk about anything relevant. We don't have sex anymore.. and I am so depressed.. I don't wanna do anything or see anyone or talk to anyone not even him. I just wanna be alone in a room forever and not get up til I go into labor. I just wish there was something I could do. I want to be happy. I'm gonna have my baby soon. I just can't find it in me...
