Oh, Zen... I'm so sorry.

Please remember that we care here and from what you said this isn't complete nor permanent. In situations like this I think about when you are in an airplane and those little masks fall down from the ceiling. You are supposed to put one on yourself and then help those who need it. He wouldn't be any good to you if he isn't okay and you want him to take care of himself right? It doesn't make it any easier and I wish this hadn't happened, but hopefully your brother is able to recharge and be able to be back in your life soon.
