As LH said, DBing early on is difficult, so don't beat yourself up too much.
The important thing is to keep trying it over and over again. I have seen many situations in this forum where the LBS has been nowhere close to even minor DB but over time they changed and started healing. You will fail but pick yourself up and try again. If you do that, you will look back at yourself in a few months and see how far you have come.
