I agree. What he did, to do that in front of you, was a passive-aggressive act of VIOLENCE against YOU.
Apply again for a RO. Tune out the brother. Who cares what he thinks?
You're gonna be OK. Breathe. He is incapacitated for the moment, and tomorrow's Monday. Try to get some rest, and start tackling the details tomorrow.
You did EVERYTHING RIGHT. I'm so sorry this happened to you.
Major hugs,
