15 and pregnant

yesterday i found out i was pregnant, and immediately i thought of an abortion. i’m poor, my family isn’t in a good place rn, i’m still in high school, and the baby daddy doesn’t care about me. literally when i told him he said he hopes i’m not “using this to get him to stay” like wow . hurt. i told my older brother and he telling me to keep the baby, that this might be the best thing to ever happy to me, that God is gonna be happy with me not making an abortion, and that he’ll help me. but what about me? ik it sounds selfish but i’m so stressed out rn i can’t have a baby, especially that BOY’S baby. but i’m scared one day it’s gonna be back to haunt me. idk what to do please help me decide .
