Verbal and emotional abuse? How can you stop it?

Well my mom has been emotionally and verbally abusing me for a few years now, I just started realizing this after years of denial and repression. But now that I have to face it, im more scared then ever. My mom will scream at me and tell me that when im in pain because of an ovarian cyst, that they will remove it by surgery so I will stop complaining. I am terrified of having surgery and I started balling uncontrolably and shaking horribly and she didnt even care. She told me I needed to go to a counsler because I was in pain, I screamed at her that my friends said she was evil and she didnt even care. She acts so much nicer around my dad and if she does yell at me my dad just ignores it. my boyfriend has had enough of her doing this to me its starting to do real damage, he’s threatening to call a social worker its getting so bad.

For years my mom wouldnt show me any love and I felt so horribly deprived of love and affection I actually had a sphycological need for it, I started looking for anywhere and I ended up almost getting my virginity taken away by some guy just to get a little bit of love. I went anorexic for a year trying to get back at my mom, but for years I coudlnt understand what was missing, it was the trust and love that my other friends get from their mom and I never did. I would stay up crying because I felt that no one loved me, and no one ever could. She yells at me for everything, I can never do anything right. She screams at me to shut up, to her I’m the biggest failure. She terrifies me now if anyone even gets a mean tone I instantly start crying, because of her I have developed horrible anxiety. I am afraid to let my boyfriend call a social worker and get relocated because I’m afraid she will really try to hit me and scream at me more then ever.

Can anyone help? What should I do?
