The finding of happy, has very little to do with other people. Take Long term Relationships, they come with allot of insecurities, as man/wife will over time push each others insecure buttons. (they become nasty over time)
Then find ways to build up your self-worth and self-love. These 2 states are your anchor in life.
You will validate and complete you. If not you will then always be the unhappy one waiting for happy that will never come.
Your happy is you, then seek it from within you ......
