idk what to do

Okay so, i really don't know how to explain this but, one day i was watching netflix until i got a text from my boyfriend (who hasnt texted me back in like a day because hes busy a lot) so i got excited and looked at his message and saw that it was actually his brother messaging me. So i asked him what happened to anthony (fake name to protect identity) and the brother said hes not doing good. And i had a panic attack and asked what happened, his brother responded saying anthony had a stroke and isnt doing well. I froze, i started crying and didnt know how to help. Mind you, they live in north carolina and i live in NY, so i didnt know what to do. On one hand, I want to text him to see if hes okay, but on the other hand, hes probably not going to read it or his brother his going to read it. If i dont text him hes going to think i dont care, but if i do his brother his going to answer. I really need help.
