I have never had a guitar lesson, and I cannot read music to save my life.
But for a self-taught guitarist, I am pretty decent.
And, my tip to you is.... FEEL the music. The rhythm will come. Start with a simple ballad. And sing it out loud to yourself first, WITHOUT playing the guitar to get the feel for the rhythm, then start again with the guitar. Note that it is painful, and you will need to play the song at least 20 -30 times before you get the "muscle memory" ingrained.
Best of luck!
