Please Help Me

Okay, so I need a little advice that I can take with a grain of salt. Let me fill you in on the last 2 months of my life. On March 15th, I gave birth to a beautiful baby boy. Previous to this, my family told me I needed to get out of New Jersey and move back home, as my boyfriends family only saw me as a vessel for Vinny (my baby). Once he was born, no pictures were posted of me and the baby, or the baby, my boyfriend and I. Only everyone else holding him. My boyfriends mom constantly refers to MY BABY, as her baby. She is psychotic too, saying how “he’s too skinny,”, “he’s not eating enough,”, “you need to supplement,”. My boyfriend told her she needs to back off, to stop saying those things, so she did... to my fave. She now talks behind my back. She told my beat friend, and I quote, “my baby is too skinny, he has no rolls. I need rolls on my baby.” He’s gaining weight fine, he just doesn’t have rolls like she would like. I’m constantly chastised for how I parent, (i.e.: responding to him too quickly, holding him too much, not supplementing). Since I’ve given birth, no pictures of me have been posted with him since easter, and that was one photo. I’ve went back to work and she watches him Saturdays. May 18th, this last Saturday, was the first Saturday she watched him. I had a mental breakdown... that morning, she took him from me and I couldn’t even say goodbye, she didn’t let me dress him, kiss him, nothing. She literally just. Took. My. Baby. Today, May 19th, we all went to a birthday BBQ, baby included. I did not hold him at all, I got him out of his car seat and she immediately took him and started passing him around like a bowl of mashed potatoes. I can tell my mental health is decreasing, my boyfriend no longer sides with me and says I’m overreacting, but she is literally a psychotic lunatic over my child. Not only is my family telling me to get out of New Jersey, immediately, but all of my coworkers as well. I don’t want my child to grow up without a father, but I don’t know how much longer I can take this.
