hmmm, it's sad that because it left you for awhile, you feel worse that it is back.
Ups and downs. I have had periods when I went from being terrified to ecstatic hourly. I have had times when life was so flat as to be mostly peaceful verging on depressingly boring.
Despair exists that we may know joy.
Stay in the now long enough and the next view promises to be even more spectacular.
