I want to leave my BF

We've been together for three years living together 1 year. And now I'm 14 weeks pregnant expecting his son.
I am exhausted of the cruel words and the lies. I am sick of crying and being hurt. I am tired of feeling like I'm doing this pregnancy alone. I'm tired of loving him and being with him..
I want to leave but I have no where to go.. I'm scared.. I think I'm depressed I'm not excited for my baby boy. Im just scared and don't feel worthy of being a mother.. I fucked up my life I don't want to fuck his up. Im scared....... 💔
