I think you should pat yourself on the back. You had a slip and got right back into sobriety, you didn't turn it into a relapse. Remember, string, add those sober days up and be proud of yourself and the hard work you are doing.
It sounds like you are reading, meditating and trying alternative methods to deal with the depression. Good for you. I suffer from depression and after all the booze was out of my system my doctor found meds to alleviate my darkness. But I practice meditation and yoga for the anxiety because I can never take mind altering chemicals like valium ever again.
Be proud!
