Just been wondering.......
I'm actually surprised that this OP doesn't have more likes. Selenah, if you spend time 'drawing close' to God and have a desire to see Him visibly and physically too-- if this desire only increases or continues while you are drawing close to Him-- then the desire is from God. David said, "Delight yourself in the Lord, and He will give you the desires of your heart" (Ps. 37:4). If you delight in Him, the desires of your heart become the desires He has for you, and so He will give them to you.
I was also 19 years old when I began to also desire to see God visibly and physically here on earth before the very end. The more I drew close to God, the more the desire in increased. This desire began after I had an encounter with God on an Amtrak train en route from Baltimore, MD to Atlanta, GA on March 28, 1998. (I recorded the incident and some other encounters with God here to encourage those who God has given desires that He may not have given others, so they don't give up or stop seeking because others may say their desires can't be had:

Luckily for me, the people I shared this desire with were all Charismatics who believe supernatural things can happen, so they agreed with me that it was possible. However, if you have desires or dreams and nay-sayers tell you that what you desire is impossible, etc., remember that it was right after Job's good friends told him that God wouldn't answer his request to meet God face to face-- right after Elihu told Job that God was too awesome to appear to a mortal man-- that God suddenly showed up just as Job desired. (Job 37:19 - 38:1.) God appeared both visibly and physically in the OT; the ministry of the New Covenant is more powerful. If others don't believe, believe. Our faith is small because we are small, but God honors faith, no matter how small it is,
if you can only believe: "Truly I tell you, if you have faith as small as a mustard seed... nothing will be impossible for you" (Matt. 17:20).
