I highly recommend mindfulness meditation its the best one I've tried. Its really hard to do on your own if you have a short attention span, try guided meditation videos on youtube. Here is a guided mindfulness meditation video I found on YouTube. If you don't like it there are like 100,000 other ones to choose from. I found the ones for insomnia to be helpful, it takes practice to learn it.



Mindfulness is essentially staying aware of your surroundings, living moment to moment and not focusing on anything else besides what is happening around you at the present moment. You sit still as possible and pay attention to your surroundings looking at everything in a non-judgmental way. If you do it enough, you learn to appreciate small things and take it all as it comes. Instead of worrying so much about the future, or ruminating over things that happened in the past you keep yourself focused on things that are happening in the present. You pay attention to feelings you are having in the present such as stress or anxiety and sensations you may have in your body such as pain and judge them as neither good or bad.

Mindfulness is really good for times of boredom as well, I can almost sit in the waiting room for my pdoc without fidgeting when I practice mindfulness.
