try taking magnesium. Most people are deficient, and it is known to be an antistress mineral. Plus when you are stressed, drink coffee/ caffeine or alcohol your body loses magnesium. Studies have shown that nearly all people who get panic attacks are deficient in magnesium, same with those who are depressed. Plus over 300 enzymes require the presence of magnesium ions for their catalytic action
So get a magnesium supplement try not to get oxide though because that's not very easily absorbed. You can try buying magnesium chloride or epsom salts and just take a bath in them every night. This is one of the best ways to absorb magnesium because it's absorbed right through your skin.
