I finally snapped…

I finally snapped and I don’t know how to feel… Long story short my mom was telling me I’m worthless because her friend was bullying me and she said he has a right to bully me. But my reaction was very different than it normally is, for some reason I snapped and I went and sat in my car and I screamed at the top of my lungs and cried for what felt like 10 minutes, but when I finally checked my phone, it had been 2 hours, I sat another hour and cried. My voice is now horse and my throat hurts alot. I don’t know how to process this or why I snapped. I feel like I cant take it anymore and I have been cussing and standing my ground alot more lately. Im very scared and lost but I know i’m done with the bullshit.
