How to not feel empty?

Make yourself into someone you can respect. Exercise increases overall mood so get to doing that normally. Find a hobby, or do hobbies you enjoy, Find a job you can enjoy(Often has to do with said hobbies.). And Finally, always do the scary thing socially. Be it adding an extra word, or walking up to someone, Builds social skills. Find some friends. Don't go headon into a relationship and lose yourself in it. Without being happy, with just yourself.

Pursuing and valuing happiness can actually lead to more disappointment since happiness can only be felt in the present moment. Paradoxically, focusing on bringing happiness to others helps bring you into the now, opens your mind, helps you 'feel' more and therefore increases good vibes~

People subconsciously know if you are trying to be someone you are not. One important thing I learned in life us that people can't like you until you like yourself.
