This is just stuff that works for me, suggested at various times by counselors and physicians (and siblings involved in health care):
1. Turn off the TV and commercial radio.
2. Eliminate alcohol intake. It's a depressant. Withdrawing from it as it metabolizes out of your system is a cardiovascular stressor and elevates the physiology of anxiety. In short, if you habitually use much alcohol, it puts your body and brain on a rollercoaster. If you use much alcohol, don't abruptly stop using it or you may have seizures. Get some help from a physician who knows something about alcohol dependence.
3. Reduce caffeine and sugar intake.
4. Get some exercise, even if it's a stroll around the back yard or the block.
5. Spend more time with people, less time online or on the phone or texting etc. Being with other people and talking with them really helps put things into different perspective.
6. Yesterday is toast, tomorrow not here yet, today's what there is and if I cannot do anything about something today, try not to rent space to it in my head! I have a still life of Buddha with an empty red bowl next to him in my library. I look up at that sometimes and take some gnarly ol' problem and visualize putting it in the red bowl. Just for now. I tell myself I can take it out when I come up with some practical way of dealing with whatever it is. Meantime, let Buddha have it and move on.
7. Count blessings or fortunate circumstances: we all have some.
8. Confide in a friend that you're a bit off top form and would he/she be honest about remarking to you on any changes in you that seem worrisome to him or her.
9. Play music for awhile every day. It's medicine since ancient times.
10. Make a difference in someone else's life: give a shirt or a pie plate or a portable radio to the Salvation Army, shovel an elderly neighbor's sidewalk or mow their lawn, go to the supermarket and scarf up stuff on one of those ten-for-ten-bucks sales, then truck it on over to the local food bank.
Well that's enough from this preachy bee. Still, this stuff works for me.
