Sorry to hear of crises of confidence, teeth etc.
Can identify with dietary worries - DD lives on shed loads of chocolate, biscuits and sweet drinks and she barely picks at meals.
DH is diabetic and never managed it himself, so I had to. We eat healthily and don't buy junk food but DD buys it for herself and eats it in her room. I don't know when she last had a piece of fruit and she barely touches vegetables. I just keep providing good food and hope. I do buy her some treats but she just eats those and leaves the good stuff
She's had two concerts this weekend. I was stuck in South Ken for 3 hours this morning between her rehearsal and concert but couldn't face the crowds to do much shopping
