I think one of best ways of handling stress is still relaxation and enough sleeping. For example, try self-hypnosis which is still quite easy and can be done anywhere and anytime even at your place of work or in the car.
And again one of the easiest technique is to focus on a word or phrase that has a positive meaning to you. Words such as "calm" "love" and "peace" "all is well" work well, or you could think of a self-affirming mantra such as “I deserve calm in my life” or “Grant me serenity”. Focus on your chosen word or phrase continuously if you find your mind has wandered or you become aware of intrusive thoughts entering your mind, simply disregard them and return your focus to the chosen word or phrase. If you find yourself becoming tense again later, simply silently repeat your word or phrase.
Don't worry if you find it difficult to relax at first. Relaxation is a skill that needs to be learned and will improve with practice no time.
And also rather than relying on medication, your aim should be to maximise your relaxation before going to sleep. Make sure that your bedroom is a tranquil oasis with no reminders of the things that cause you stress. Avoid caffeine during the evening, as well as excessive alcohol if you know that this leads to disturbed sleep. Stop doing any mentally demanding work several hours before going to bed so that you give your brain time to calm down. Try taking a warm bath or reading a calming, undemanding book for a few minutes to relax your body, tire your eyes and help you forget about the things that worry you.
You should also work towards going to bed at roughly the same time each day so that your mind and body can get used to or adapted to a predictable bedtime routine for you.
