I'm so scared of having this baby!

So I found out I was pregnant a few weeks ago and I have no idea what to do/feel. I am 20 years old and a freshman at UCLA. I'm considering keeping the baby, but I have no idea how I'm going to care for this child once it's out. I don't really have anyone to take care of the baby while I'm at school (dropping out isn't an option) and overall I'm just scared of not being able to do this. At the same time i really want this baby and an abortion doesn't feel right. Anyone else going through this? Or have any advice?
