Just woke up freaking out

It’s 4:15am and I just woke up to sounds of my brother gagging* and throwing up, I run out to the hall absolutely freaking out, he tells he he’s drunk and that’s why he’s s* but only had 5 drinks… could that be why? He’s pretty skinny but still… I also am just freaking out and idk what to do my emetiphobia has been at an all time high this year :( it’s super bad timing
