Hi Bryan,
The main thing is that you are sober now and good for you for being sober for a year. Blaming yourself for the past won't help.
And, yes, in my opinion you should not let your discomfort come into this, and you should call your daughter more often. It sounds like she trusts you and would benefit by talking to you. This should be a chance for you to help her through a tough period. It's too bad you can't drive to see her, but is it possible to take a bus to visit? Be a shining example to your daughter and show her what a sober life can be.
