What do you do when you realize how unfinished you still are?

I get depressed about it. Haha. Especially when I was convinced I'd given 100 percent. But lately I've started thinking that I don't have to call self-sacrifice love. The people I love might want me to be happy too. I'm human, so sometimes I fall apart. I really do. Then I try again. For me, that cycle is probably part of how I've become a little stronger.
