1. I'm sorry, that musts suck. I hate it when my dad yells, i used to hyperventilate when he'd yell when i was younger

2. Ways i calm myself down is just listening to music, putting on headphones/earbuds and just laying in bed, focusing on the music. Idk if it'll work for you

3. It's not your fault

4. I read your post whenever i come across them, I just don't know what to say, I've never really been the comforting/consoling type

I hope things get better soon. Take care
Byee
