I’m gonna lose it today!!!!!!

I am on my period cramping and trying to deal with my boyfriends dad that keeps making comments about my weight. He has said I look as fat as a hippo and I needed to stop eating. I’m so over it. He does this shit ever time I’m around him. Or he call me dumb. I just keep getting told say something because it’s not my place. We’ll its funny because i told my mom off and choose my boyfriend over her many times. He also hates her and says she’s not allowed around him because she says things to him he doesn’t like. Well should I do say the same about his dad? His grandma treats me like shit also by showing me his ex all the time. Man I thought today would be good. Haha guess not
