Doctrine and Covenants 84:88
And whoso receiveth you, there I will be also, for I will go before your face. I will be on your right hand and on your left, and my Spirit shall be in your hearts, and mine angels round about you, to bear you up.
This is a scripture has helped me a TON on my mission so far. I can truly testify that you as well as I, are watched over each and every day of our lives, and we need not fear when we have faith in one greater than us.
If you ever feel like you are alone and are lost, know that you can pray at all times, and in all places to one who loves you and cares for you. Because he is your literal spiritual father.
