News is because recently I don't know if you've been following #feesmustfall but its been a huge movement here. One I felt that I should have been more involved in, and that many of my friends have been. I've been glued to the tv watching them getting stun grenaded, rubber bullets shot at, and tear gassed. Its hard not to when you're emotionally involved, and you're so worried about your friends.
If possible lie down somewhere, close your eyes and focus on your breathing. Also if you can, listen to music or the radio and focus on what they're talking about/the music. I suffer from the odd panic attack myself and this how I usually calm down.
