It’s OK

it’s ok to doubt. if you’re not sure if what you’re hearing is really from the Lord, ask Him. this happens in both the Old and New Testament. Gideon and Thomas asked for proof; Gideon wanted to know if what the Angel of the Lord was telling him to do was really God and Thomas wouldn’t believe that Christ rose from the dead until he could see it for himself. in both cases, their doubts were dissolved.
but here’s the kicker … you’ve got to move! once He has shown you it’s really Him, you’ve got to do as He has commanded (even if it sounds absurd) 

Gideon said to God, “If you will save Israel by my hand as you have promised— look, I will place a wool fleece on the threshing floor. If there is dew only on the fleece and all the ground is dry, then I will know that you will save Israel by my hand, as you said.”‭‭ Judges‬ ‭6:36-37‬

Now Thomas (also known as Didymus ), one of the Twelve, was not with the disciples when Jesus came. So the other disciples told him, “We have seen the Lord!” But he said to them, “Unless I see the nail marks in his hands and put my finger where the nails were, and put my hand into his side, I will not believe.”‭‭ John‬ ‭20:24-25‬
