Hi everyone, 
When I was out to lunch at the park on this GORGEOUS day I was thinking about Ami and GainingStrength, and of all the stories of heartbreak and pain I am getting to know on this site -- you all get to me, your really do, each and every one of you -- and thought I'd share what I have found so helpful. 
For me, music is the proof of God's existence, and I have found enormous strength and comfort in a few particular hymns and texts from classical church liturgical music. 
The first is a "little" hymn, meaning that the text is simple and so is the melody -- but this is my favorite hymn, and I always sing it to myself, especially when I'm lost and can't find my way out. I don't know what it is about this hymn and text, except that it is such a spirit of humility ... but I love it. I sing it quite often, and during Lent I sang it three-four times in succession each day as a devotional. It is mystical. Something happens when you sing it like that. It brings me, at least, to a place of, usually, great pain and despair, but then that is replaced by peace and hope and calm. You can find the tune at 
www.cyberhymnal.org (I think that's it.) 
The text is by Synesius, Bishop of Cyrene (c.365-414 ?). The tune is "Southwell." 
        Lord Jesus Think on Me
        Lord Jesus, think on me
        And purge away my sin;
        From earth-born passions set me free
        And make me pure within.
        Lord Jesus, think on me
        With many a care opprest;
        Let me Thy loving servant be
        And taste Thy promised rest.
        Lord Jesus, think on me
        Amid the battle's strife;
        In all my pain and misery
        Be Thou my Health and Life.
        Lord Jesus, think on me
         Nor let me go astray;
        Through darkness and perplexity
        Point Thou the heavenly way.
        Lord Jesus, think on me
        When floods the tempest high;
        When on doth rush the enemy,
        O Savior, be Thou nigh!
        Lord Jesus, think on me
        That, when the flood is past,
        I may the eternal brightness see
        And share Thy joy at last.
        Lord Jesus, think on me
        That I may sing above
        To Father, Spirit, and to Thee
        The strains of praise and love.
There is another little-used verse that I often put up front:
      Lord Jesus, think on me:
      And this poor offering
     Which I do humbly weave for thee
     Accept, O Christ my King.
The other piece I like is from Mendelssohn's (will I ever be able to spell his name?) Elijah, which uses text from Isaiah. It is very comforting to me, particularly with M's musical setting (I think I'm right about it being from Elijah). 
      Cast thy burden upon the Lord,
      and He shall sustain thee;
      He never will suffer the righteous to fall
      He is at thy right hand
      Thy mercy, Lord is great
      and far above the heav'ns.
      Let none be made ashamed
      that wait upon Thee.
Hope no one will mind my going a little astray and a little religious; it's just that I find such peace in these and thought others might as well. 
Have a great weekend, everyone!
