Are you spending too much energy on getting involved in the lives of others? If so, you are depriving yourself of the attention that you need to be happier and feel more content. Going out with friends and having fun is a perfectly fine thing to do, but you should not be doing it every single night. All of this socializing could distract you from the things that you really need to deal with. Stay home more often and help yourself get back in touch with yourself.
