We learnt to meditate in Middle School R.E. classes as a break from Bible lessons. We mainly did visualisation techniques but sometimes had to draw what we saw afterwards. After my Gran died when I was in High School I got headaches & migraines for 10 months which I later found were caused by worrying too much & getting too upset. Painkillers didn't work. They put me on Sanomigran to take everyday to prevent them. All it did was make me sleep. Peppermint tea & meditation worked a lot better.
