its not only how you act, time for sleep, its how you feel about yourself inside that shows on the outside.. a lot of people can act a certain way for a certain period of time, but inner truth stays with us, when we are down, and when we are up and it is very difficult to mask our true feelings... see if you can find some hobbies or activities that increase the good feelings you have for yourself.. it will naturally show on the outside... just a general rule of thumb... positive actions create positive thought, which in turn, creates more positive action
