Keep your best-loved guitar. Use it to TEACH. Teach beginners their first chords, teach kids, teach whoever. Put a 3x5 card up at the nearest market, church bulletin board, wherever. Get hold of the music dept. or music teacher at your local middle school and high school. "Half hour private guitar lessons, any level, $25. Call xxx-xxxx." You can do it at home, and it keeps you doing music, which you clearly love, even though not on the level you are capable of. In two hours a day you can make $200, if you can work your way up to four students a day. Best of luck, don't give up.
