CrazyK,
You will need the support of your family to go on with this pregnancy. The best thing for you and your baby is to stay in school and get a education - the first and foremost important thing that you will teach your child as a parent. Next, you will need financial support, how do you expect to get this?
Why would you not want to tell your parents that you were pregnant? Do you feel they will not support your decision? Yes, you are young and as yet still need to be guided yourself. It is a huge responsibility raising another life made even bigger by the fact that you want to be a big girl and live on your own and try to do this when you do not even have the means to find your information that you require from the internet yourself?
Do you even know what a baby all requires? Do you know what living in a household with a baby, a boyfriend and yourself while all working entails? Do you know what being mature means? You got yourself into this situation at a young age and you will never get your youth back what are you and how are you going to teach your child about being mature and responsible? Choices you make in life are permanent.
You could consider an open-adoption with a caring family that still allows you contact with your child. You could consider grandparent rights to help raise child until you are of age and maturity that allows you to be a proper parent to this child. You have a lot of growing up to do if you think that you can raise a child yourself without help.
I'm sorry that I am ranting about this pregnancy with this question but I just read your other post to find this post after. Please think about this and reconsider your options before you make the final choice to do this on your own.
Hope this helps (even if it is not what you want to hear) and good luck.
