Starting over- without a teacher

You will be fine just make sure you keep your right hand always swinging to the pulse and get the chord changes under your belt. However do not be disheartened if the first time you try and sing and play it all goes a bit aschew...... that it is a seperate skill as many people here will be able to tell you.
I have started using my metronome to keep myself honest about tempo. Yes, I have noticed that keeping track of the strum and the lyrics timing is difficult for me. Keeping away from any song containing an eight note. Or simplifying the strum to one per measure.
