Idk what to do.. 😔

I'm literally at my breaking point.. Before I get into my details I'll start from the beginning. My mom and I have never got along. We argue over the littlest of things and the pettiest tbh. I HATE it. I'm a very bubbly positive person and my mom is the total opposite. She never understands me, if I have a panic attack or if my depression comes lurking back in she thinks I'm doing it for attention and rolls her eyes and says people have bigger problems than I do. Obviously there is people that need help but it would mean a lot to me if a mother can listen to her own daughters cry for help and advice, well.. I'm never going to receive that from her than being yelled at. Images from how we gotten into an argument still haunt me a bit.. I don't like talking about it much but my voice needs to be heard.. She had gotten my pillow, it happened so fast and I couldn't breathe. I told her to stop and she wouldn't. She finally did, though, it happened once after this incident. If anyone has went through abuse please tell a person you trust or your local authorities. You deserve to live in a positive amazing life away from toxicity.
