It's my 2nd year in college and most of the time it was online which was fine, but it was face to face today. 

I was feeling okay. Although I did almost cause an accident because I was freaking out. 

But made out of my car and was about to head into the classroom until something just kicked in and a was again in my car on my way home. 

And then the professor says there will be a presentation and attire is "professional" and I was about to switch my entire major just because I thought I didn't have a nice enough shirt, but when I finally calmed down I realized that I have like 2. 

It has been and emotional rollercoaster today

Has anyone else ever felt or done this?
