I think it's just all part of the process. Emotions hit (good, bad, ugly, FUBAR) and we have to deal. One of my self-help books I read had a quote that I try to remind myself something like "acknowledge the feelings, challenge the thoughts".
We feel what we feel and don't really have control over what goes through our minds and hearts, but how we think about it, react to it is completely in our control. It's ok if it's bothering you, just don't let it own you.
