Making "Me" Happy

Whenever I'm asked 'what makes you happy?' it always seems to involve another person. I'm someone who always seems to put others needs above my own, regardless of my happiness. Even when I ask myself now 'what makes me happy?' I always picture someone else in my head before me. I don't get it. I'm sure someone else out like is like me and can tell me these things and what I should do, but at this point, I'm just lost.
