I have learned that happiness is not something that can be found; it is merely something that is a result of things going as they should in your life.
If you are not enjoying yourself or feeling lonely in crowds of loved-ones, then there is something you are not addressing within; however, sometimes the way you feel is merely the you-of-the-time and you should not stifle yourself in any way.
Feel the way you feel naturally with no shame in it. There are no wrong feelings, only wrong actions. Dwell in that darkness for a bit and come out of the other side stronger.
Wonderful comic.
