Sounds EXACTLY the way I feel about my daughter's piano practice. I wanted to nurture her (perceived) talent. I bought a piano. I payed for the lessons. I go to the concerts. But listening to her practice is like nails on a chalkboard. I grit my teeth, listen and tell her what a good job she's doing - but I can't wait for it all to end. It's worse than listening to school readers. There's stuff you do for them that you don't love. But you do it for them anyway....because you do love them....It's normal for us to feel a bit over it from time to time. Don't think I am making light of the way you feel- I have been there myself. but sometimes I think we expect to much of ourselves. You have been brewing some awful bug for the last days by the sound of it - that's bound to make you feel worse.
