Is it normal to feel this way?

my 26 year old friend, Kai, had recently not been talking to me. this morning i found out he was in a traumatic motorcycle accident and has been in the hospital. although im only 16, we're still close since we were in the hospital together for almost a month and kept each other company. i know its not right but i feel a little betrayed. i feel like he should have called me or something (its not like he couldn't have). the only reason i know is because his college called me. i havent talked to him about it cuz i feel guilty as hell feeling like this. i completely understand why he didnt tell me, im just a kid after all, but i still feel angry about it. is it normal? should i talk to him about it? how do i stop feeling this way? its ridicules. i want it to stop because i want to be there for him right now. could someone help me? what should i do?
