So worried...

He didn't go home last night. There was no one at his place. And his handphone is still off. I managed to get through at 3 AM, but after that he turned it off again. I didn't really sleep much. I went to bed at 12, woke up at 2+, slept at 5+, and woke at 9. I talked to David for those 3 hours, and he made me feel better. But this morning I can't stop the tears from flowing again. Where is he? His friends have no idea where he is, nor did he contact them at all. I really am at a loss. I sent him so many messages but he never replied to a single message.
