never go to bed angry

I was always told to never go to bed angry because when you wake up the feelings will still be there and you might grow this kind of resentment towards them. and some people believe that, but only because they hear it a lot so they think it is true. studies has shown it is not. when you sleep after being hurt, heartbroken, or just plain mad, you are just preserving your emotions. you are not hiding them or building them up, you are just saving them for another time. some people even say they cant sleep during the night when something bad happens. and that is because them thoughts are there just wondering through your head. I'm still not saying it is good because it is not. i believe you should speak your mind to make your self feel better and to get stuff off of your chest so the person you have a conflict with knows what is really wrong and if he or she really cares they will try to fix it. even if they don't try to fix it get it off your chest anyway. it will make you feel better and you will not have them thoughts in your head and you will not have to go to bed angry. but eventually you will have to talk about what is upsetting you because if not you are going to blow up.
