<human>: Can you succinctly summarize the text in 1-3 sentences?

Throwaway account for obvious reasons.

Here is the situation: (I'll try and keep it short and to the point)

My boyfriend went to a christmas party at his best friend's relative's house.   His original plans were to go to the party, then drive to his cousin's house tonight because he has a flight really early in the morning (he's going on a mini-vacation with a few family members).

We had been texting all day (as usual; I'm out of state visiting family for Christmas) and it kind of tapered off once he arrived at the xmas party (for good reason, who wants to be rude and text ya know?).  At about 9pm the texts kinda stopped but I figured it was because he was either having fun chatting with people or driving to his cousins (about a half hour drive).  I was busy with family stuff anyway.

  I asked him how things were going around 11pm and he responded at about 12:30am saying "I am the worst person ever."  I, of course, replied asking him what was going on and if he was alright.  He still hasn't responded and it has been (a very long) hour.  I have called him twice and he hasn't picked up.

 I absolutely hate jumping to conclusions but my mind is going crazy and I honestly don't know what to do right now.  I really hope he didn't get into an accident or do something worse.  

It's now 1:30am and his flight is at 6am.  I can't sleep.  Help me reddit.
<bot>: Boyfriend texts me saying he's a horrible person after going to a christmas party. I can't sleep because I'm worried about him.
