I cant decide if I want an abortion or I want to keep my baby?

I'm only 16.I have big dreams. I know I shouldn't have been having sex , but I did. I was on birthcontrol,however my antibiotics for strep cancelled them out. My bf & family support me in whatever I choose. I have severe depression & I think I have bipolar. I have hurt myself many times before & I'm afraid I'll hurt the baby. I have to stay on my abilify because my doctor says the pros outweigh the risk. I'm scared if I have the abortion,I'll regret it. I'm also 11 weeks along. I need any advice please & thanks :)
