Need some advice with my pregnancy?

Everything is out of control, given I'm not a teen I'm not an adult either I'm 20 still living with my parents and it seems everything is kind of spiraling out of control. I've always been an insomniac until I found out I was pregnant since then I've been relieved to be able to put my head down and actually fall asleep but now the problem is that I never wake up. I will sleep til 4-7PM without being disturbed and usually when I wake up I don't feel tired again til early in the morning 3-4AM. Because I sleep so much I'm missing most if not all my meals. Breakfast and lunch mainly and the snacks I should be eating in between. I also cannot keep track of my pre natal vitamins and they make me sick as hell! If the eating thing was all I am faced with I'd be ok but My work hired in a ton of new girls and the summers are slow business so I've only been working 3 days a week at waitress pay. If that wasn't bad enough I'm only a part time student now so all of my loans are rolling in. I'm facing 50$ a month and yeah thats not bad but it is when my checks bi weekly are 30-50 on top of the 5,000 in medical bills I've managed to stack up in just 9weeks. I'm just looking for guidance, not lectures. My parents really don't want me considering adoption but they always talk about how they are going to have to raise this baby and it makes me feel like crap. They talk about not wanting to, and I don't want them too either, but I know I will need their help...but then they give me a hard time when I mention adoption and say that they don't want to raise the baby but they will if they have too. + They always seem to downgrade me now. Since I'm the youngest of me and my brother they've always talked about how proud they were..now it's well your brother is going to school and works alot! "You always sleep then use pregnancy as an excuse" that line irritates me because I really cannot help sleeping so much It's frustrating! I still attend school too! and I would work more if I could but no one wants to hire me because as soon as I'm done training at the new job I'd have to go on maternity leave. With everything going on I feel like I'm going batty!
