How can I make a difference for the Lord and not live just an “ordinary” life?

[EUT20 #10] I have consecrated everything to the Lord, I love Him, I only want to go on for Him alone, taking His way and so on, yet I don’t feel like the Lord is using my consecration. I am afraid that I would just live an “ordinary” life which is totally what I see myself doing right now, studying, getting married, having a family… That’s never what I wanted. I wanted to be radical for the Lord, making a difference for Him, going “against the tide” for Him, even turning the age! But never to live day by day such an ordinary life that mostly doesn’t seem to differ that much from how lukewarm believers who don’t care for the Lord or even some non-believers live. Before I came to the church life, I even felt a lot more useful to Him than I do today. The problem is, I know I myself can’t change anything, because it’s the Lord who needs to use my life and my consecration, but it doesn’t seem like He does (anymore). I have been told that the Lord needs “ordinary” people and that the normal life is the Christian life, but I want more than that for the Lord. I am not satisfied yet unable to change a thing. Maybe you could say I feel like a Hannah without a son and I am afraid of living an average life for the rest of my life. I am so frustrated and stuck. Please help.
