forgot the appointment

Today I had a very important appointment but I forgot that it was for today. I thought that my appointment was for tomorrow morning but when I checked the appointment letter I found that it was this morning. I was worried and when I read the letter it said that I could go Wednesday at the same time. I do not know what I was thinking. I think I lost my mind already or I was only getting excited about the appointment that is why I got confused. I hope this Wednesday I will make it or else I will get in trouble. I need to stop thinking a lot and focus the important things.
