Awkward socially

I hate ending up in awkward social situations, where you don't know more than one person and people are talking and talking and you don't have anything to contribute to the conversation. So you just end up sitting there saying nothing. Which is weird. And awkward. One of those situations where you want to excuse yourself politely and run away to normalcy.
I hate sitting here, saying nothing. But there is nothing to say, and nothing to contribute, which sucks because I want to visit with my friend but they're busy socializing with other people.
Meh, call me Silent Sam

One of those nights

The problem with working graveyard shift is that very few people are on the same schedule as you. The other problem is that when you switch between nights and days working your brain gets confused. I'm now very awake at 3 am wanting to talk or do something with a friend but I'm pretty sure all of them are asleep and I don't wanna be the person who texts "are you asleep?" at 3am waking someone up. I feel that's a dick move, since most everyone is asleep at 3am or they are actively trying to fall asleep.
My brain is busy. Tired, but busy. Too much thought. It's getting all confused about life, money, work, plans.. Yadayada
If I was sleeping normally anymore I would just go to bed, but my sleep is still all screwed up. Don't know why I can't sleep normally anymore. I'm amazed I haven't crashed yet from sleeping so little for weeks and weeks.
Oh well, nighty night world, I'm going to try and get some sleep. Wish someone was awake though...
