HI Kristina, first of all congratulations on the upcoming birth of your brand new baby girl and know that this child is and will be a blessing in more ways than you will be able to count.
As far a career path goes, you have find what interests you most or maybe think about what you wanted to do before you became pregnant. Those goals are still possible, it might be a bit more difficult, but still attainable. You might want to take a look at the job market and see what you would like to be doing. However, whatever path you decide to take, do it right away, do not put it off, because the longer you wait the more difficult it will be to go back to school.
I don't know what kind of support system you have, but if it's there, use it. Also, you may want to look into what colleges and universities that offer daycare for students. I just want to let you know that having a baby at 18 does not mean that your life and the things you wanted for yourself is over. Your most important job now is taking care of yourself and your baby, everything else is secondary. Please know that part of taking care of yourself means going to college or a technical school where you can get the tools you're going to need in order to give your child the best life possible. Just remember, she didn't ask to be born, so she deserves the best from you. I hope this helps.
