pregnant with no support

i’m 18 and 6 weeks pregnant. i went to get an abortion yesterday but once i was about to get on that table i couldn’t do it, i started hysterically crying and the doctors let me leave, my mom and boyfriend were in the waiting room when i got out and were very disappointed that i didnt go through with it, it was a very traumatic experience at the clinic and i cant believe theyre still begging and pressuring me to go back and try it again. My mind is made up, im keeping the baby and no one can stop me. it just sucks because this whole pregnancy im going to be alone and i know once the baby is born then they will love it, theyll regret pushing me to kill it.
My problem is that my mother and boyfriend fight, hes not allowed over my house and his parents are currently not letting me over their house for many reasons. My mom said i can live in her house so i am until i get enough money to move out into a cheap apartment where i can live quietly and stress-free.
Do you think i should just ignore everyone around me until they come around and be a little nicer, because all this screaming and stress/anxiety might cause me a miscarriage.

I dropped out of community college and i dont have a job, my goal right now is to find a full time job and work until the day that baby is born. I have no idea what to do about my boyfriend, him and my mom cant stand eachother, they cant even be in the same room, so immature! my boyfriend said im ruining his life on purpose and hes begging me everyday to get an abortion, and he said if i dont get an abortion i better not make him pay child support and hes taking the baby to live in his home because he thinks im unfit to raise a child properly (being hes the one who wants to kill it).

How do you teen moms do it without the fathers help or anyones really? Have you all started out in my situation? does it get better or easier? How did you get money in time for the baby?
