I came across this great talk today and am copying my favorite parts.
The condition of the physical body can affect the spirit. That’s why the Lord gave us the Word of Wisdom. He also said that we should retire to our beds early and arise early (see D&C 88:124), that we should not run faster than we have strength (see D&C 10:4), and that we should use moderation in all good things.
In general, the more food we eat in its natural state—the less it is refined, and the fewer additives it contains—the healthier it will be for us. (Cadbury eggs??) Food can affect the mind, and deficiencies in certain elements in the body can promote mental depression.
A good physical examination periodically is a safeguard and may spot problems that can be remedied. Rest and physical exercise are essential, and a walk in the fresh air can refresh the spirit. Wholesome recreation is part of our religion and is a necessary change of pace; even its anticipation can lift the spirit. (note to self sign up for October Marathon!)
The fellowship of true friends who can hear you out, share your joys, help carry your burdens, and correctly counsel you is priceless. For one who has been in the prison of depression, the words of the Prophet Joseph Smith have special meaning: “How sweet the voice of a friend is; one token of friendship from any source whatever awakens and calls into action every sympathetic feeling.” (Teachings of the Prophet Joseph Smith, comp. Joseph Fielding Smith, Salt Lake City: Deseret Book Co., 1938, p. 134.) (Send Jill thank you note for listening to me yesterday)
Ideally, our family ought to be our closest friends. Most important, we should seek to become the friend of our Father in Heaven and our brother Jesus the Christ. What a boon to be in the company of those who edify us! To have friends, one should be friendly. Friendship should begin at home and then be extended to encompass the home teacher, quorum leader, bishop, and other Church teachers and leaders. To meet often with the Saints and enjoy their companionship can buoy up the heart. (go to church today and stop worrying about the fact you may or may not look pregnant)
When George A. Smith was very ill, he was visited by his cousin, the Prophet Joseph Smith. The afflicted man reported: “He [the Prophet] told me I should never get discouraged, whatever difficulties might surround me. If I were sunk into the lowest pit of Nova Scotia and all the Rocky Mountains piled on top of me, I ought not to be discouraged, but hang on, exercise faith, and keep up good courage, and I should come out on the top of the heap.” (George A. Smith Family, comp. Zora Smith Jarvis, Provo, Utah: Brigham Young University Press, 1962, p. 54)
There are times when you simply have to righteously hang on (hurry warm weather) and outlast the devil until his depressive spirit leaves you. As the Lord told the Prophet Joseph Smith: “Thine adversity and thine afflictions shall be but a small moment;
“And then, if thou endure it well, God shall exalt thee on high.” (D&C 121:7–8.)
To press on in noble endeavors, even while surrounded by a cloud of depression, will eventually bring you out on top into the sunshine. Even our Master Jesus the Christ, while facing that supreme test of being temporarily left alone by our Father during the Crucifixion, continued performing his labors for the children of men, and then shortly thereafter he was glorified and received a fullness of joy. While you are going through your trial, you can recall your past victories and count the blessings that follow if you are faithful. And you can have that certain knowledge that in due time God will wipe away all tears and that “eye hath not seen, not ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.” (1 Cor. 2:9.)
