I have found EFT very helpful if I feel anxious or stressed at work. I used the downloaded guidance document from the EFT site and currently sign up to its newsletter. (the download is free) It think the site is something like www.emofree.com (haven't been on it for a while as I receive the newsletter instead). The instructions are very clear in the booklet. Just make sure you read through all the advice before you start. Gary Craig (EFT founder) highlights how important it is to understand the process fully before you use it. It's a very gentle and effective procedure which merely requires repetition and a bit of perserverence. It appears to involve a combination of affirmation/auto-suggestion with stimulation (through light tapping) of key acupressure points to activate a change in ingrained physiological reactions to certain thoughts or situations including those characteristic of a phobia response (symptomatised both physically and emotionally).
Give it a shot and see what happens.
Kind regards
