Today has been almost as bad.
I accidentally got on the wrong bus this morning. I've taken the same bus almost every day for more than a year. But I was standing at the gate in the station, a bus came from the opposite direction most of them do, just like usual. I looked at it from a distance and it looked like it said 43, my bus. It was the right time for the bus. It pulled up and I was looking down to get my money, and I didn't look up in time to see that I was getting on the wrong one. Then I couldn't decide what to do once I realized we were going the wrong way. My boyfriend had my phone because he doesn't know his route to work as well. I was too afraid to ask anyone to borrow a phone, but I couldn't tell him that. I knew he wouldn't understand my choice to stay on the bus for a while either, but I just thought it would intersect with something useful, that would get me to work more quickly than backtracking. I had no clue where I was but I kept hoping I'd see an intersection or another bus I knew. Finally I just got off and went across the street to catch it back in the other direction. It didn't come for an hour. I ended up getting off it a mile from my transfer station and walking there so I didn't have to go all the way home and start over.
My boyfriend is more mad than my boss. He says they'll fire me if I keep doing this. (I've never done this before but a couple of times I've missed my bus. Not too recently. The last time I was late we were driving my mom's car and traffic was just horrendous.) He says I was careless in not checking the bus sign before getting on it. He does every time, he says. But he goes a lot of different places. I've been doing this for a year, I didn't expect anything to be different. Of course that's not an excuse.
There are no excuses. I feel like I'm losing my mind. My boyfriend pointed out that at this point I'm screwing up worse than our schizophrenic roommate, at which point I hung up on him because I don't know what I would do if I had to keep having that conversation. I know it's rude, and I know he thinks it's just because I was mad at what he said. I wasn't mad, he's right, and I had already had that thought, and hearing him say it was like a knife through my heart. I don't know what's wrong with me.

Just now at work I did something I've never done, too. A customer pulled up and I recognized him as he got out of the car, so I ran the racks around to where his stuff is. That I do when I recognize a customer. But I also always tear the invoices off the orders before I walk them up front, because when I started I used to forget to take them. And for some reason today, I started tearing off invoices from other people's orders that were next to his, thinking they were his too! I didn't even notice until the second one.
I feel like my brain is full of holes.
What's happening to me?
