I am at a loss right now

I really am at a loss for what to say tonight. I experienced God tonight leading worship, and had a great time with friends of mine after. I am amazed at the awesome God I serve, but even after all of that, I still feel empty. I don't know what it is, I just know that even though God is with me, I just feel abandoned and empty. If anyone out there feels led to say a prayer for me, I would greatly appreciate it. I just pray that God will reveal himself and that he will fill my heart to overflowing with his grace.
