I don't know if anyone else have ever experienced this about waking up in the morning being very pissed for a reason you can't figure out. I always feel like it's bad energy around someone that's the cause of it because it happens to me once in a while. It will take hours before I'll be able to break out of that feeling of madness.
What I noticed is that I wake up angry when I've had a poor night's sleep. It also happens to me when I'm feeling very overwhelmed with some responsibilities.
This happened to me when I was at my previous job. I was so unhappy at my previous job that I often woke up angry and I spent every minute of my work day angry.
I'm much happier at my current job that I've been at since last September.
