Advice Needed

I planned to go and get an abortion on Friday. My mom and my boyfriend tried to convince me not to. My mother even went the extent of having my aunt come over so I decided not to go threw with it. But as I lay in my bed at 2:00 in the morning I can't help but think that I am making the biggest mistake of my life and that I do not want this baby. It hurts cause I know a mom isn't supposed to feel like this , but what am I to do. I have to give up my body for another 5 months not anyone else and I have to live with that baby for the rest of my life. I'm stuck.
