I'm very on edge today. Keep thinking about things I don't want to be thinking about, but I can't seem to stop the intrusions. I'm exhausted, which is making everything worse. Today is my last day of work for the week, and I'm afraid of how I'll make it through. Things shouldn't be too complicated, but I still have this overwhelming feeling that something huge is going to go wrong today, and I won't be able to fix it.
