It is difficult to be truly open and attentive to the Lord's call unless we are at peace. Any desire for God in your heart was placed there by Him, and He will fulfill that desire in His own way and His own time. So do not worry. God really does want you to know His will for you, and He will show it to you in His time. Entrust your vocation to our Blessed Mother, asking her to guide you and to share with you her own spirit of loving “fiat” to whatever God may ask.
