It sounds to me like you just need a little time to get used to playing the guitar with the capo on.
The thing to remember is, once you put the capo on, you want to pretend the capo is the nut of the guitar. And with the capo on, you will make your chords exactly the same as before, counting your frets up from whatever fret you have put the capo on.
In this case you would be putting the capo on the 2nd fret. So now the 2nd fret is like the nut, the 3rd fret is the 1st fret, the 4th fret is the 2nd fret, and the 5th fret is the 3rd fret, and so on.
The thing about using a capo is it gives you a LOT of flexibility with very few chords. You can transpose your songs into whatever key feels comfortable and still be playing the basic chords that you know and love.
