I don't know what's going on

     I don't know how I ended up where I am lately. I'm back into this ugly funk, where I feel like no one wants to be around me. I know this isn't really true. It's just... People around me have their own personal lives, and I'm still used to sometime who demanded I spend every minute with them. Last night, I had several bad dreams about people telling me to go away. They ranged from me being a child, and hearing "This is grown-up stuff, go play," to being myself and having friends point and laugh while I say in a corner away from everyone else.
     I just can't seem to shake this. Even though I know the truth is merely that I live on a different schedule from the rest of the world. But would it change if I could get off of night shift? I don't like these feelings, and I don't know how to deal with them anymore. And I don't know how to tell this to the people who are around me.
     All it took to set me off this time was a situation involving some friends, but not me. I was having a good time hanging out, until they needed to discuss their problem. I was very politely asked to give then the necessary privacy, but I still went from having social contact, to being trapped by myself again. A few minutes turned into the entire night and hours of bad dreams.
     Now it's early in the morning. Everyone else is doing their thing, such as sleeping. I'm watching TV and debating whether to go out for breakfast by myself
