Never forget you have been called by a prophet of God!
The challenges you face are very similar to the challenges faced by those in the early church who were called to serve missions: homesickness, problems at home, discouragement and despair, people that don't have ears to hear, loneliness and temptation.
But the foundation of truth is the same: The gospel of Jesus Christ - faith, repentance, baptism, receiving the Holy Ghost and enduring to the end, teaching by the Spirit, opposition, people searching for the truth, and the Lords missionaries!
3 Nephi 22:17

"No unhallowed hand can stop the work from progressing; persecutions may rage, mobs may combine, armies may assemble, calumny may defame, but the truth of God will go forth boldly, nobly, and independent, tell it has penetrated every continent, visited every clime, swept every country, and sounded in every ear, tell the purposes of God shall be accomplished, and the Great Jehovah shall say the work is done."
