Searcher, I know what you're going through. It was agonizing as a teenager to read all those New Era stories about kids getting burnings in the bosom or feeling wrapped in God's love, while I got nothing. The one bright spot was when an elderly lady got up in testimony meeting and said, "I don't know that the Church is true, and I probably won't know in this life. But I believe it with all my heart." So I decided that I could just believe, and be ok.
But it really wasn't enough. I finally gathered my wisps of faith and decided to make a leap of faith. The fact was, I couldn't hear God. We could speculate why until the cows come home, but that wouldn't change the reality. So my thought process went like this: I choose to believe that there is a God, and that He loves me. If there is a God, then He knows that I can't hear or feel him, except perhaps in the mildest, most indirect way. If He loves me, then He wants to communicate with me in spite of my limitations. Therefore, He will answer my prayers indirectly, in a manner that I can perceive.
So I started looking outside of myself for answers to my prayers. And you know what? I found them. And my wisps of faith grew thicker. I now have to courage to pray with the hope that my prayers will be answered, one way or another. I occasionally even get impressions that I think come from God, so I act on them accordingly.
