Pregnant

So... Yesterday I took a pregnancy test and it was very positive. I'm 18 and still studying my boyfriend is 21,working. I don't have a strong connection with my mom, or any in the family... My friends are in my age obviously so they wouldn't know much. Since I am studying, I wanted to do an abortion. It's still what I think is the best.... But I am afraid? What will I be missing out? Will this haunt me? Will I live on and forget? If I keep it....Is it super hard financially? Is a baby too much? Anyone
 I don't know where else to write this...
