Hi, I struggled for a long time on some of the chords. But i worked on the mantra, that if i made that chord just one time i could with time and practice learn to make it everytime.
I also spend time switching between two chords for two minutes and writing down how many i did in a minute, that way is encouraging as you do eventually see those numbers go up.
maybe try em to e chords, so only one finger moves, then e to am, so all the fingers move down one string.
Small wins will give you a big boost of confidence.
