Write down your feelings. Keep your thoughts short and concise. Use color and imagery to enhance the words on paper.
Transform your thoughts to lyrics in a song. Tell your sad story in verses, and put a catchy chorus between them.
Grab your guitar and mess around with easy chord progressions. G, C, D or E, A, D are country favorites. Have one chord progression for the verses and a second, similar chord progression for the chorus. Keep it simple, and change the chords and words until they make a country boy well with tears.
Add a bridge to your song. A bridge is usually played with minor chords, like E minor, G minor or A minor, and fits between your second verse and chorus. Write the few, to-the-point lines that you couldn't fit into the verse or chorus. Again, focus on details while writing the bridge. Describe exactly how it feels to lose something you love.
Sing your song when you begin to feel lonely, lost or sad.
