16 and the pregnancy struggle

Please don't judge me, I know I have no business being pregnant at 16. I found out I was pregnant August 2nd and ever since my life is just falling apart. My family doesn't care for me no more and my boyfriend recently left me and our unborn child. I'm scared, I don't know what to expect. I love my baby more than anything already and I don't want to give her up to another family, but I have no job and I don't want her to hurt her whole life because I decided to get pregnant young. I don't know how to seek help in this situation, I want to keep my baby and be the best mom possible. Been trying to get a job since I've been pregnant and its harder than I thought. I really need advice from those of you who been through similar.
