Euphoria is an intense feeling of happiness or excitement.Euphoria is a state where you have no control over your emotion because your emotions are so heightened. Euphoria is often used when describing side effects about a "high" because you are not in your right mind set. Basically just a unmeasurable amount of excitement and sheer ecstasy. Although there is a difference between happiness and euphoria. Happiness is to be at peace with where you are & what you have. To find the joy in the little things & to let go of negativity. People can have everything & not be happy, because they haven't found peace.
