Try these sites for more instruction. Don't be so hard on yourself. It does help to have an instructor; so it figures if you are doing it on your own it will take longer and be more difficult. Maybe you can have your parents post here or any of the other sites; then we can explain the benefits of taking lessons. BTW, I'm 47 and taking lessons; I could only go so far on my own.http://www.chordmelody.comhttp://www.guitarforbeginners.comhttp://www.wholenote.comhttp://www.guitar.comhttp://www.guitarsite.com
