17 and pregnant with twins

I am 17 and I just found out today that I am having twins. I am so overwhelmed and just exhausted. It all seems like so much. I struggled with accepting the one baby and I finally got excited and now that I found out I'm having twins, it just seems so much more difficult. I already work two jobs and take classes at a community college and I don't know what more I can do. I don't know if I can afford to let go of one of my jobs. I'm going to have to stop going to classes and I will have to give up one job because I just work so many hours. Ugh. My boyfriend works two jobs as well and is still in high school and I just don't know how we're going to pull it off. I have no female support so that's why I'm here. I have no family except for my cousin who I live with. I'm just overwhelmed. I'm so sick all the time. I feel like this pregnancy is just taking such a toll on my body. I'm exhausted and bloated and I vomit all day. I don't know how I'm even going to carry these babies for so long. Sorry for venting.
