In addition to relaxation breathing and guided imagery, one great self-help technique that you can use anywhere (even while sitting in a chair in your office or while seated anywhere), is progressive muscle relaxation.
We've put detailed instructions on this on my website's Self-Help page just under the Guided Imagery.
Use it whenever you feel the need to get a bit of relaxation. It works very well because you can't be anxious and relaxed at the same time and this technique uses that idea very well.View Thread
Exercise is one of the most beneficial self-help techniques we know of today and more and more research is indicating its usefulness in changing mood, decreasing anxiety and even helping keep the brain physically healthy. You don't need to go to a gym or even have any equipment because you can walk in place, walk up and down stairs or use simple items like a book or a can of vegetables to do arm exercises. You can do just a bit a day and gradually increase what you can do. Keep at it and you'll notice a change for the better. Remember, even if you don't feel like doing it, do even just a little bit and fight that urge not to do it. In the end, it works to your benefit. Trust me on this one.View Thread
