I would say I have felt happy. I could say I feel happy now, it's meaningless because I don't really know what it means. I am not at all trying to be a downer. That is not my intent at all. I, at this point in my life am trying to really figure out what happy means. I can't honestly use the term until I have a deeper understanding of it's meaning. To say I am happy about something is really just nonsense.
