Have your sugar levels checked......you could be low - if my husbands sugar drops too much (he's reactive hypoglycemic) he will get emotional and have crying spells over nothing! Are you eating right....if you can't get your blood checked right now, try eating something every 2 or 3 hours, crackers, cheese, peanut butter - banana's, balanced meals, plus the snacks and see if that helps any. If it does, then it's your sugar levels.
