Today was a little strange, I got home feeling fine, and I recently bought a capo for my guitar, this thing changes the key that you guitar can be played in by holding all of the strings down on a single fret. I was really excited to learn a new song that required the capo and I had worked on that for the majority of my day. About 30 minutes before I was meant to go to taekwondo, I felt really light-headed, and my heart was racing for no apparent reason. I have heart palpitations, so my mom, who's in the medical field, was worried and wouldn't allow me to go to taekwondo today.
