What is happiness?

I have had an unsavory education through my life. My life has been focused on what others need from me - emotionally, financially, etc.. What is always lost in every relationship is that I am a human and I feel emotion deeply. That I have needs, that I have things that I want to accomplish. That I too want to feel love, support, appreciation. Maybe I'm naive. Or immature in the deep reciprical soul connection that I believe love to be. Maybe this is the role. Maybe this is an expectation because I am a man. But, I find it difficult to be content or happy, when the expectation has been throughout my life (since childhood) that I am to facilitate the needs of others and no one should find my own needs of any import. I'm trying not to be selfish. Trying to stop believing that my own hopes, dreams, desires, concerns, fears, longings are of any value at all. Only those of others. But, in this, I'm also trying to understand what happiness is.
