Hey dude, you have the same problems every guitarist has when they start you're normal man! Do you know all your simple basic chords in the open position? If you can spell the word C A G E D with them then you do.
Try to do each shape ..for example the D shape and replace the notes that would have been open notes with your index finger.Remember to keep the same distance between the fretted notes and play it high up on the guitar.
Barre chords in the E shape are not really the easiest to play and if you play higher on the guitar its a bit easier since the frets are closer tgether.Work your way down the fretboard slowly with one shape until your reach the point where it starts to get tough. Reemember also that barre chords like F in the E shape are a real pig for any guitarist starting out.
