Conflicted

Nothing in life is all black or all white. Especially in my life. That is probably why I always find it so difficult to make a decision. And that is probably why I always end up feeling conflicted about the decision I took. I never feel completly happy or completly sad about it. And I don't know what this "in-between" state is called. I don't know what I feel. And having people on one side telling me they can't wait to see me and people on the other side telling they wish I wouldn't leave doesn't help. Am I doomed to miss people (on one side or the other) for the rest of my life? Will I always be under the impression that my life is cut in half and be wondering forever where I fit in? How am I supposed to reconcile two parts of my life that seem so unreconcialiable?
