Panic attack...

It’s been a hot minute since I’ve had a full on panic attack like this. To make a long story short, my brother was a recovered addict and my dad kicked him out the other night for no reason. He called me while he was looking for a place to stay (I live out of state) and he sounded so hurt and broken. I haven’t heard from him since that call, two days ago. I’m so terrified, I can barely stop crying. I’m not even religious but I’ve been repeating a prayer and begging god if there is a god to not let my brother die. My other brother died a couple years ago, and I honestly dontthink i could handle losing another brother. I don’t know what to do with myself, I can’t sleep or eat, I feel paralysed and scared...
