Dear thisisfine,

OH my, this new baby and you will have a big age gap.
How do YOU personally feel about the situation, do you think that your mom is pressuring
you as you havent mentioned a father figure (yours/new b daddy)?

As for school, try not to pre worry over things.
"I'm making these things bigger than they should be."
Yes and No. It is a matter of perception that makes things feel the way we do.

What concerns me is, this is your life, soon 3 years school will be over, and you will have more power and control.
Everyday a little bit stronger. You are the author of your life and only you can change.
Be responsible and go to college/hold off pregnancy for the next 10 years. Find a passion for the arts /history/culture.
I hear in your tone the need to escape from xyz and take a breath, that sounds wonderful, how can you make that happen? Nothing is impossible.

TRY to talk to someone about your thought process.
Or come here, lots of people who are going through similar things, use their age and wisdom to help benefit yourself.
