Should i get an abortion, or keep it

I just found out i’m pregnant. I’m really fucking broke and don’t have my own place. i’m 20 years old. i still have 2 years of college left. should i abort, or keep, if i get an abortion i will literally hate myself but if i keep it i will literally not be able to afford it. i also currently have an infected wisdom tooth and i have to get all four of mine removed. and i’m prescribed penicillin. my mom thinks i should abort but supports either way. i can’t tell my dad right now. my boyfriend doesn’t know what to do
