I need advice...

So my fiancé and I honestly have been together less than a year and we have our baby boy on the way. As much as I love this baby with all I am already it seems I've been falling into depression with all this and not really feeling like I know who I am anymore, on top of that my fiancé and I have been arguing more, his family hates my guts right now for things i couldn't control, if i bring up even the conversation of me doing any type of "job" or ways to bring in money to help us it's an instant fight and i just really feel like the bad guy ALL of the time then he rushes to talk to his mom about our arguments, troubles, anything... I can't go anywhere on my own or hardly see my family alone and when I do get to see them Its not long before he wants to leave. I don't know how to cope with any of this anymore.. i need help and I hope this post is allowed.
