Just feel so worthless

My sons dad and I got in an huge argument. It started out with him drinking again. But then turned into other stuff. He started going off about how I’m just better off about being a sahm because I don’t do anything/make any money. I work in a salon I’ve only been out of school a few months and we just opened the building so I’m still building a clientele. And I just got a second job at a brewery to make extra money in the mean time. But to him it’s not good enough. He says that I have nothing to show for because he was 21 when he bought a house and I’m 23 and have nothing. I’ve been really stressed with my work and have been feeling like I’m failing and now it’s like he just confirmed it. When I moved in he told me not to worry about the bills he’ll take care of it and I just pay for groceries and whatever else but he just throws in my face everything he pays for and that I don’t contribute to anything. I’ve given him money before to help out but he’ll always tell me it’s not enough. I’m just at a point I feel what’s the point of me even being here. I guess since I don’t do anything. I’m not worth anything. I have no friends. I love my son but he’s just such a daddys boy he doesn’t pay attention to me. So he’d probably be better off not having a mom as worthless as me anyways. My sons the only thing that keeps me going anymore but it’s hard when I feel like he loves&rather be his dad more than me. Just don’t know what to do anymore. I’ve never felt this low.
