I found a quote from Howard W Hunter that described my feelings:
"Sometimes we may feel that our spiritual edge has grown dull.... We may even feel that God has left us alone in our confusion and concern."
The answer to this makes sense, and I'm going to work on it.
"But that feeling is no more justified for the older ones among us than it is for the younger and less experienced. God knows and loves us all. We are, every one of us, his daughters and his sons, and whatever life's lessons may have brought us, the promise is still true: 'If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him.'"
The answer is to pray and ask God, choosing to believe He can and will actually answer me about the things that I care about and are very relevant to me. I pray, but I think I feel dull because I may not have been believing. Here's to a sharper edge and a new excitement for life!
