first time mom, single, and afraid

My baby girl is due in exactly 3 months. I'm beginning to stress myself out. I don't know what's going to happen. I'm on the verge of losing my job but I wanted to work on weekends when she got here. I stay in a house I pay all bills. Im on a waiting list for a apartment that's based on income but the waiting list is 4-6 months long. I tries to speak with my mom about my situation and me coming to stay until I can figure something out but b4 I could even ask she but told me I'll figure something out like she knew where I was getting at. I have no support system. All I do is cry because I don't know what's going to happen. Any advice out there?
