Dear Universe: What's the deal?

I am one of those people who will do anything for you. I wasn't always like that, but the universe has changed my ways. I figure I can let go of my old selfish self and embrace the newer healer and helper. That's a magnificent idea. Except today I feel selfish again, and I kind of think the universe owes me a little. I have lost my family, and a few friends. I have given up one career to take up another. I have given up relationships so I can have a career. So now that I am settling into this new life the universe has given me, I feel like I deserve a little personal attention.
I have put my heart on my sleeve in the past, just to have the universe swipe it off like a fly. And today feels no different. Just when I thought the universe was telling me it was safe to get back out there and be vulnerable, a big stop sign shot up in my face. What kind of karma does a girl need to cultivate to have love in her life?
