Yesterday a mom of a friend died and at the funeral I felt really sad about everything, when I was back home I  cried till I fell asleep.

But I didn't make a lot of things that I had pending because I was out, and today when I realized how much behind I am (because I had planned everything that I had to do everyday to finish on time) I started to feel really weird.

Like I couldn't see really well, everything was blurry and too bright, my head started to hurt really bad and I felt really light like I couldn't stand anymore.

I just lay in bed and fell asleep and now I feel better, but I don't know what that was.

Was that an anxiety attack or something else?
