30 weeks and extremely depressed

is this normal? I feel like I'm crying everyday. I'm scared to be a mom, im scared of labor, i feel so distant from my boyfriend, i feel so sad all the time, i feel like I have no one to turn to to talk about my feelings. I'm constantly broke and I selfishly look towards my boyfriend who makes more then me and I feel bad for asking for help and feel worse when he tells me no. he tells me if i want more money to figure something out bc when the baby comes hes not paying my half of rent (180) and he's not helping with any of my bills. I feel mad at him and shitty at myself for even asking. I just feel so dumb, so fucking dumb.
