Yea, I had that problem for the longest time! I just found that it was happening because God wasn't a priority to me. I prayed and read my bible as a last minute thing, I did it when I had time, when I should have been making time for it. I just think about it like this, the God who created the whole universe wants to have a relationship with me, why am I shunning him to a last thought? And just pray that God will teach you how to listen (btw, I'm not saying that what I described is you, I am just saying that's what it was like for me)
