I dont know what to do...

I am 18 years old and I am pregnant for about 3 weeks, I do not know if I should abort or give in adoption to the baby. I feel very guilty for ending the child's life, I even started watching videos on ultrasound and listening to the beats of a 3-week fetus. I feel too guilty for wanting to have an abortion but I definitely do not see myself having a baby at such a young age and leaving school. That's why I've thought about giving it up for adoption, but I really do not know what to do.

Could someone tell me their experiences with abortion or giving a child in adoption?
