Overwhelmed

I'm in my final year of uni and just found out I'm 8 weeks pregnant. I was on birth control so it's come as a serious shock. I haven't given myself time to process the news since I've been immersing myself in my senior project purposely because everytime I think about it I get really upset. I want to be happy about this blessing but the fact that I don't have much of a support system in place is pushing me towards an emotional breakdown. How will I afford proper healthcare or prepare properly for my child and finish uni as well? The father seemed on board but he's suddenly distanced himself and I haven't spoken to my mom about it because I'm feeling too fragile to deal with her criticism and disappointment,especially considering I don't have an income and she may have to step in until I do. I'm overwhelmed dealing with the changes in my body particularly the emotional ones,the moodiness,bloating and horrid morning sickness,all alone. I just want to scream. Please advise.
