Hello Heather. I am really sorry you found yourself in this situation, and I do hope it all works out for the best. I do find you to be a strong person, as I quite clearly remember what life was like when I was 17, and I knew back then I could not handle a child, and was one of the reasons I abstained from sex for as long as I did.
I do think there is something that you have said a couple of times that I think you should reconsider, which is this:
...and especially in my case since I don't have financial issues...
The fact is that you DO have financial issues now, especially if you are planning on keeping the child. I can understand you thinking this way, though, since in the same post you mentioned this:
I mean, I've never even had a job before and have basically had things handed to me.
While I am sure your parents will be more than willing to help you and the baby out I would not consider this a permanent situation. I would also reconsider the idea that because of their willingness to help this alleviates you of any financial obligation. I am also assuming that you are not familiar with your parents financial situation. I know it may APPEAR that they are economically stable, but as someone who works at a financial institution and looks at bank accounts day in and day out this may not always be the case. Unless you have intimate knowledge of their credit cards, loans, mortgage, 401k, etc I would not rely solely on them for years to come.
For what you have said, I think adoption would be your best route this late in the game. You are handling the situation itself with grace and maturity, but you can tell just by your writing that you still are, very much, a teenager. And while having a baby forces you to grow up, you seem to have the foresight that motherhood may not be something for you.
I have a friend who had a child when she was 17 that she gave up for adoption. She said it was the best worst decision she had to ever make in her entire life. She actually still keeps in contact with the family, and visits them once a year. The adoptive parents are young, successful doctors. THEY are financially stable. THEY have the means to care for a baby. Teenagers, even with the support of their parents, generally do not.
I know this is a horrible decision to make, and I wish you the best. Having a baby is tough. I am sure whatever decision you make will be the right decision for everybody in the end.
