"Surely he has borne our griefs, and carried our sorrows; yet we did esteem him stricken, smitten of God, and afflicted. But he was wounded for our transgressions, he was bruised for our iniquities; the chastisement of our peace was upon him; and with his stripes we are healed." Mosiah 14:4-5
Jesus Christ has borne our griefs, and he know how we feel. He has "gone forth, suffering pains and afflictions and temptations of every kind; and this that the word might be fulfilled which saith he will take upon him the pains and the sicknesses of his people...and he will take upon him their infirmities, that his bowels may be filled with mercy, according to the flesh, that he may know according to the flesh how to succor his people according to their infirmities." (Alma 7:11,12) He has suffered all so that we don't have to.
Elder Holland of the Twelve Apostles helps us understand this point:
Jesus loves you and because of His love for you he suffered everything you can imagine and more. Come unto Him and He will give you rest.
