TITLE: My [22 F] gay, best friend wants to adopt my baby. I am [19 F].
POST: I broke up with my boyfriend and had to move back home with my mom. I fell pregnant and have been thinking about getting an abortion. My female friend is a lesbian and wants to adopt the child. She said she will end the friendship if I don't. 

My appointment to terminate is tomorrow. Not sure what I should do.

Keeping the baby will mean strain on me, prevent me from going to college next semester, likely affect my health and ability to have kids. I am on medications that I cannot take while pregnant that keep me from having mental break downs. 

I don't want to hurt her, she is like my sister, but I cannot carry this child to term. How do I break it to her gently?
TL;DR: 
Best friend is gay and wants me to give her my child. I cannot because of medical issues. She doesn't understand, says she will end friendship over it.
